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.
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
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.
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.
33 has the factors ,3, & '11' ; it is composite 43 has no factors ; it is a prime number 63 has the factors 3,7,9,21 ; it is composite.
I would say composite cos it can't be prime. prime is no which can only divide to aone nd it self but 63 can divide by 3!!!!!!!!!
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. 43 is a prime number.
The correct answer is D 63. A composite number is a positive integer that has at least one positive divisor other than one or the number itself. 0 is not considered a composite number. 19 is a prime number, as it has only two distinct factors: 1 and 19. 1 is a unit and not considered a composite number. 63 has factors other than 1 and 63 (specifically, 3, 7, 9, and 21), making it a composite number. So, the correct answer is D 63.
It is prime
