The GCF is 5. Method: Because 3045 is such a large number, find the prime factors of 50 and check whether any of them divide into 3045. The prime factors of 50 are 2, 5, and 5. 3045 ÷ 5 = 609, which is not divisible by another 5, since it does not end in 5 or 0. Nor is it divisible by 2, since it is not an even number. Therefore, the greatest common factor of 50 and 3045 is 5. (3045 = 3 x 5 x 7 x 29)
