Question

4. Find the least number which when divided by 112, 140 and

168 leaves remainder 8 in each case.
​

Answer 1

NANBA..

That is, 840 × 2 = 1680 is the lowest number which is the lowest common multiplier of 112, 140, and 168. In order to get the remainder 8 when divided by 112, 140, and 168, we need to add 8 to 1680. Therefore, 1688 is the ANS...

Answer 2

Answer:

Method: LCM ( Lowest Common Multiple )

Prime factors of  112 = 2,2,2,2,7,1

Prime factors of 140 = 2,2,5,7,1

Prime factors of 168 = 2,2,2,3,7,1

LCM : 2x2x2x2x3x5x7x1 = 1680

Ans to Q = LCM + remainder (8) = 1680+8= 1688
