138 is a composite number. This is because composite numbers are any number that has more than two factors(one and itself). Therefore, since 2, 3, and 6 among others are factors of 138 that makes it a composite number.
Composite since it ends in an even number it will always be divisible by 2
Composite
1, 2, 3, 6, 23, 46, 69, 138 2, 3 and 23 are prime. 1 is neither. The rest are composite.
138 is not prime. 138 = 2 * 3 * 23
