Prime
1 is special 2 prime 3 prime 4 composite 5 prime 6 composite 7 prime 8 composite 9 composite 10 composite 11 prime 12 composite ext.
Composite since it ends in an even number it will always be divisible by 2
1, 2, 3, 6, 23, 46, 69, 138 2, 3 and 23 are prime. 1 is neither. The rest are composite.
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.
138 is not prime. 138 = 2 * 3 * 23
138 is a composite number because it has factors other than 1 and itself. It is not a prime number. The 8 factors of 138 are 1, 2, 3, 6, 23, 46, 69, and 138. The prime factors of 138 are 2, 3, and 23. The prime factorization of 138 is 2 x 3 x 23. NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
