Then, identify the factors common to each number and multiply those common factors together. To find the gcf by prime factorization, list out all of the prime factors of each number or find them with a prime factors calculator. Each number has two 2's and one 23 in common, so we will use those numbers.

Find out the gcf of 18 and 24. 2x^2 (1 + 3x) + 5x^7 (1 + 3x) note that there is a common factor, 1+3x. Multiply those factors both numbers have in common. They have factors 2 and 3 in common so, thus g.c.f of 18 and 24 is 2 × 3 = 6.
