To find:

L. C. M

Solution:

we have to find the LCM of 63 , 84 , 28,70​

so the division table of 63 , 84 , 28,70​

    Division Table

2   28  63   70  84

2 14 63 35 42

3 7 63 35 21

3 7 21 35 7

5 7 7 35 7

7 7 7 7 7

1 1 1 1

Now,

LCM = 2 x 2 x 3 x 3 x 5 x 7

LCM = 1260

Hence,

LCM(28, 63, 70, 84) = 1260
