The prime factors of 38 are 19 and 2. Since 1 isn't prime or composite, 1 cannot be a prime factor of 38.

I can't draw a factor tree here 76 / 2 = 38 38 / 2 = 19 Prime factorization is 2, 2, 19

79 is a prime number. There is no common factor (other than 1) with 38 (whose prime factors are 19 and 2)

76 is an even number so it is divisible by 2, so 2 is the first prime factor.76/2 = 38, and 38 is an even number divisible by 2, so 2is the next prime factor.38/2 = 19, and 19 is a prime number, so 19 is the next prime factor.The prime factorization of 76 is 2 x 2 x 19.

2 and 19 are the prime factors of 38
