LCM of 49, 21, 70, 621

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

LCM of:

Least Common Multiple of 49,21,70,621

Least Common Multiple (LCM) of 49,21,70,621 is 304290

3 49, 21, 70, 621
7 49, 7, 70, 207
1, 7, 10, 207

∴ So the LCM of the given numbers is 3 x 7 x 1 x 7 x 10 x 207 = 304290

Least Common Multiple of 49,21,70,621 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 49,21,70,621 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(49,21,70,621) = 1

common factors(in case of two or more numbers have common factors) = 147

GCF(49,21,70,621) x common factors =1 x 147 = 147

LCM(49,21,70,621) = ( 49 × 21 × 70 × 621 ) / 147

LCM(49,21,70,621) = 44730630 / 147

LCM(49,21,70,621) = 304290

∴ Least Common Multiple of 49,21,70,621 is 304290
