The largest prime factor of 38 is 19.

582, 29Note: 29 is a prime number

38 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.

Considering that 100 = (2^2)*(5^5) and 38 = (2^1)*(19^1), we can see that 2 is the greatest common prime factor between 100 and 38. If the question meant the greatest prime factor of either 100 or 38, then the answer is 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.
