Factors of 585: 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585.Factors of 180: 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180.GCF (585, 180) = 45
117. First, find the prime factorization for 234 and for 585. It may be helpful to include all prime numbers up to the highest factor in the listed factorization, even if a particular prime number has to be listed as to the zero power: 234 = 2 x 32 x 13 = 21 x 32 x 50 x 70 x 110 x 131 585 = 32 x 5 x 13 = 20 x 32 x 51 x 70 x 110 x 131 Then, to find the greatest common divisor, take each factor the fewest number of times that it appears in either factorization. So the greatest common factor will include 20, 32, 50, 70, 110, and 131. The greatest common factor is thus 20 x 32 x 50 x 70 x 110 x 131 = 117.
Least common multiple of 45 and 65 is 585.
LCM(13, 45) = 585
The GCF of 21, 49, and 84 is 7.
