LCM of 80, 69, 21, 245

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

LCM of:

Least Common Multiple of 80,69,21,245

Least Common Multiple (LCM) of 80,69,21,245 is 270480

3 80, 69, 21, 245
5 80, 23, 7, 245
7 16, 23, 7, 49
16, 23, 1, 7

∴ So the LCM of the given numbers is 3 x 5 x 7 x 16 x 23 x 1 x 7 = 270480

Least Common Multiple of 80,69,21,245 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 80,69,21,245 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(80,69,21,245) = 1

common factors(in case of two or more numbers have common factors) = 105

GCF(80,69,21,245) x common factors =1 x 105 = 105

LCM(80,69,21,245) = ( 80 × 69 × 21 × 245 ) / 105

LCM(80,69,21,245) = 28400400 / 105

LCM(80,69,21,245) = 270480

∴ Least Common Multiple of 80,69,21,245 is 270480
