Best Answer

composite

. 57 divided by 3 is 19. (Any number in which all the digits add up to equal a number divisible by 3 is divisible by 3. 5+7=12 which is divisible by 3.) And since 57 is divisible by more numbers than just 1 and itself it is a composite number.
57 is a composite number since it can be divided by 3.

57/3 = 19
Composite.

57 = 19 x 3

Since 57 has another factor in addition to 1 and itself, it is composite.

57 is a composite number. A Prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name.
