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
Composite, because it is divisible by other numbers that 1 and itself.
63 has more than two factors and so it is a composite number.
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.
composite
prime
Prime number
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.
63 is a composite number. That's because a composite numbers is any positive number which is not a "prime number". This means that a composite number can be divided exactly by another number which is not 1 or the number itself. So 63 is a composite number because it can be divided exactly by 3, by 7, by 9, and by 21. A "composite" of any kind is made up of parts, just like a composition in music has been composed by a composer.
It is prime
86 is not a prime number, so is a composite.
63 is a composite number
composite number. 9x7=63
It is a composite number.
63 is a Composite Number.
It is not a prime nor a coposite. It is a composite number, though.
13 is a prime number, 63 is a composite number. 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.
13 prime 63 composite 61 prime 31 prime Well the question should have been either, Which one of these numbers is not a composite number? Or, Which one of these numbers is not a prime number?
3 and 7.
63 is a composite number. 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 has more that two factors: 1, 3, 7, 9, 21, and 63)
No. 63 is a composite number with two unique prime factors. 63 = 3 * 3 * 7
It is a composite number because it has more than two factors
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.
