no, because it has a 2 at the end. if the last digit in the number is an even number, then it is not a Prime number. Also if the only factors of the number is 1 and itself then it is a prime number. example 1: 5,622 = not prime number.... example 2: 13=prime number because the only factors are 1 and 13.
No. It is a factor but is not a prime number, being 2 x 7. Prime factors are 2 x 2 x 2 x 7 x 7
The prime factorization of 392 is 2 x 2 x 2 x 7 x 7 or 23 x 72.392= 2x2x2x7x7
They are: 2^3 times 7^2 = 392

392 is composite. All whole numbers ending in two are composite except for the number 2 itself, which is prime.
392 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.
No it is not. A prime number is only divisible by 1 and itself, whereas 784 is at least divisible by the number 2 as well. 784/2=392
No, you can tell by the last digit being divisible by two, that the number is divisible by two. Thus it's composite.
No. It is a factor but is not a prime number, being 2 x 7. Prime factors are 2 x 2 x 2 x 7 x 7
2 × 2 × 2 × 7 × 7
The prime factorization of 392 is 2 x 2 x 2 x 7 x 7 or 23 x 72.392= 2x2x2x7x7
392 = 2^3 * 7^2 so the square factors are 4 and 49.
392 = 2 x 2 x 2 x 7 x 7.
They are: 2^3 times 7^2 = 392
2 x 2 x 2 x 7 x 7 = 392
2 x 2 x 2 x 7 x 7 = 392
