The number 55 is divisible by 1, 5, 11, 55. For a number to be classified as a prime number, it should have exactly two factors. Since 55 has more than two factors, i.e. 1, 5, 11, 55, it is not a prime number.
"A common definition of a prime number is that it can only be divided by 1 and the number itself. For example: 13 is prime, because the only numbers that divide into 13 are 1 and 13 itself. 6 is not prime, because it can be divided by 2 and 3 as well as 1 and 6.
Solution: The factors of 55 are 1, 5, 11 and 55.
Definition: A prime number is a whole number with exactly two integral divisors, 1 and itself. The number 1 is not a prime, since it has only one divisor. The number 4 is not prime, since it has three divisors ( 1 , 2 , and 4 ), and 6 is not prime, since it has four divisors ( 1 , 2 , 3 , and 6 ).
Now, for 1, the number of positive factors is only one i.e., 1 itself. So, number one is not a prime number and one is not a composite number also. Therefore, 0 and 1 both are not a prime number. Note: A prime number or prime cannot be divided by any other numbers without leaving a remainder.
Answer and Explanation:
All prime numbers are odd, except the number 2. That is because all prime numbers are numbers that can only be divided evenly by itself and 1.
55 is divisible by 5 as it has 5 at ones place, but not by 10 because digit at ones place is not 0.
55 has more than two factors which are 1,5, 11and 55 and hence it is the composite number. 55 is the odd composite number and it is not the perfect square also. If we divide 55 by 1, 5, 11 and 55 then we get remainder as zero. Hence, 1, 5, 11 and 55 are the factors of 55.
According to the definition of prime numbers, any whole number which has only 2 factors is known as a prime number. Now, the factors of 2 are 1 and 2. Since there are exactly two factors of 2, it is a prime number.
A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. Numbers that have more than two factors are called composite numbers.
Answer: 93 is not a prime number but a composite number because it has more than 2 factors.
Yes, 1 is an odd number (or is it?)! All numbers that aren't divisible by 2 are odd numbers. This includes 1, 3, 5, 7, 9, 11, 13 and so on.
2 is a prime number because its only factors are 1 and itself.
The given sequence is a series of consecutive prime numbers. → The given series is 39, 41, 43, 45, 47, 51, 53..... The next prime number in the given series would be 59. This is because 59 is divisible by 1 and itself.
55 (fifty-five) is the natural number following 54 and preceding 56.
The factors of 110 are 1, 2, 5, 10, 11, 22, 55, and 110. 110 is a composite number, which means it is a positive integer that can be created by multiplying two smaller positive integers.
What are the multiples of 55? Multiples are the values that we get when a number is multiplied by consecutive natural numbers. The first ten multiples of 55 are 55, 110, 165, 220, 275, 330, 385, 440, 495 and 550.
It is easy to tell that the following are multiples of 11: 22, 33, 44, 55, etc.
We know that a number is divisible by 5 if the unit digit of the number is divisible by 5 or it is zero. Therefore, 5555 has unit place 5 and it is divisible by 5.
Every number has atleast two factors that is and i t s e l f (other than which has one factor). hence no number is there which has no factors.
2 is the smallest prime number. It also the only even prime number – all other even numbers can be divided by themselves, 1 and 2 at least, meaning they will have at least 3 factors.
No, 99 is not a prime number. The number 99 is divisible by 1, 3, 9, 11, 33, 99. For a number to be classified as a prime number, it should have exactly two factors. Since 99 has more than two factors, i.e. 1, 3, 9, 11, 33, 99, it is not a prime number.
Answer One: No.
By the usual definition of prime for integers, negative integers can not be prime. By this definition, primes are integers greater than one with no positive divisors besides one and itself. Negative numbers are excluded.
