The factors of 784 are 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, and 784. The prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7.
2 2 2 7 7 392 = 2*2*2*7*7 or 23*72
392 = 2^3 * 7^2 so the square factors are 4 and 49.
72 *23
2 x 2 x 2 x 7 x 7 = 392
2 x 2 x 2 x 7 x 7 = 392
392 = 2 x 2 x 2 x 7 x 7 OR 2^3 x 7^2
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.

The positive integer factors of 392 are: 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
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.
392 is composite. All whole numbers ending in two are composite except for the number 2 itself, which is prime.
