Question

Find the prime factorization of each of these integers and use each factorization to answer the questions posed. The greatest prime factor of 39 is _____.

Answer 1

prime factors are the factors of given numbers which are only prime numbers

that means given number should be written in the multiples of only prime numbers

if given integer is even number then we need to start divide with 2 if it is an odd number then we should use the divisible rules for each number based.

here given number is 39 and simply we know it is odd number and divisible by 3

so we can write 39 = 3 x 13 and both are prime numbers so we can write further multiples

so the prime factors of 39 = 1 x 3 x 13

and the greatest prime factor of 39 = 13
