the GCF is 117
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 225 and 585 is 45
It is: 39
The GCF is 15.
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.
5 x 13 = 65 2 x 3 x 13 = 78 2 x 3 x 5 x 13 = 390, the LCM
LCM(13, 45) = 585
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
Least Common Multiple (LCM) for 65 117 is 585
