Answer 1

Step-by-step explanation:

Find the LCM as follows

12 = 2 x 2 x 3

35 = 5 x 7

21 = 3 x 7

LCM = 2 x 2 x 3 x 5 x 7 = 420.

Next add 6 to 420 to get 426 as the answer.

Check:

426/12 = 35 as quotient and 6 as remainder. Correct.

426/35 = 12 as quotient and 6 as remainder. Correct.

426/21 = 20 as quotient and 6 as remainder. Correct.
