What is the LCM of 42 and 98?

What's the Least Common Multiple (LCM) of 42 and 98?

Answer

LCM of 42 and 98 is

294

First common multiples: 294, 588, 882, …

294 is divisible by both: 294 ÷ 42 = 7, 294 ÷ 98 = 3 — and 7 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/42 by 7 and of y/98 by 3.

42 = 2 × 3 × 7

98 = 2 × 7²

Prime	42	98	Highest power
2	2	2	2
3	3	—	3
7	7	7²	7²

— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

LCM = 2 × 3 × 7² = 294
