LCM of 20 and 50 and GCF of 20 and 50 (Show all work) (explain the steps you took to find the LCM and GCF)

"In order to get the Least Common Multiple of 50 and 20 we need to factor each value and then we need to choose all of the factors which appear in any column and then multiply them."

50: 2 55

20: 225

LCM: 2255

The (LCM) is: 2 x 2 x 5 x 5 = 100

"To find the Greates Common Factor (GCF) of 20 and 50 we need to factor each value first and then choose all the copies of factors and then multiply them."

20: 255

50: 55

The GCF is: 2 and 5 so you need to multiply and then you will get The Greates Common Factor. The greates common factor is: 2 x 5 = 10
