They're all multiples of 3.
The LCM of 18, 24, 36 and 42 is 504
The GCF of 12, 18, 36, and 42 is 6.
6
First, find the greatest common factor (GCF). 18 factors to [2 3 3] 42 factors to [2 3 7] Common factors [2 3] GCF = 6 Now, multiply them together and divide by the GCF to get the LCM. 18 * 42 / 6 = 126 ■
The common factors of 36 and 42 are 1, 2, 3 and 6 36: 1, 2, 3, 4, 6, 9, 12, 18, 36 42:1, 2, 3, 6, 7, 14, 21, 42
The GCF is 3.
If you mean 18, 42 and 36 then the GCF is 6
The Least Common Multiple (LCM) for 6 12 18 is 36.
The common (note term) factors of 42 and 36 are 1,2,3, and 6.
The common factors of 150 and 42 are: 1, 2, 3, and 6
The LCM is 9324.
The greatest common factor of 42 and 150 is 6.
