What is the Least Common Multiple (LCM) of 36 and 12? other than zero.
|
36; b/c 3x 12 = 36, and 36 x1 =36
|
|
What is the LCM of 50 and 120?
|
600: do the tree method. 50 =2x5x5, 120 =3x4x2x5, What do they have in common? 2x5. Now take 2x5x5x3x4=600, you only use 2x5 once. get it?
|
|
What is the Greatest Common Factor (GCF) of 40 and 140?
|
20; different from LCM. 40=2x2x2x5, 140=2x2x5x7. The common factors are 2x2x5. this = 20. The 20 is found in both 40 and 140 when factoring.
|
|
