Is 63 a prime or composite number?

Answer 1

not a Prime number as it’s divisible by 1, 63, 3, and 21

Answer 2

63 has factors other than 1 and itself, so it is not a prime number. For example, 63 is divisible by 3. (You can check this by adding the digits of the number: 6 + 3 = 9. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 63 is a composite number.

Answer 3

63 = 3 x 3 x 7, so it is composite

You can easily check for divisibility by 3 and 9 by adding the digits of the number. If the sum of the digits (6 + 3 = 9) is divisible by 3, then the number itself is divisible by 3. If the sum of the digits is divisible by 9, then the number itself is divisible by 9.
63 is a composite number because it has more than two factors

Answer 4

Composite, because it is divisible by other numbers that 1 and itself.

Answer 5

63 has more than two factors and so it is a composite number.

Answer 6

If it has any more factors in addition to ' 1 ' and 63, then it's composite.

Factors of 63 are 1, 3, 7, 9, 21, and 63.

Looks composite to me.

Answer 7

A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 63 is composite.

Answer 8
