Least Common Multiple of 72, 21, 43, 802 with GCF Formula

Least Common Multiple of 72,21,43,802

Least Common Multiple (LCM) of 72,21,43,802 is 8690472

2	72, 21, 43, 802
3	36, 21, 43, 401
	12, 7, 43, 401

∴ So the LCM of the given numbers is 2 x 3 x 12 x 7 x 43 x 401 = 8690472

Least Common Multiple of 72,21,43,802 with GCF Formula

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

We need to calculate greatest common factor of 72,21,43,802 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(72,21,43,802) = 1

common factors(in case of two or more numbers have common factors) = 6

GCF(72,21,43,802) x common factors =1 x 6 = 6

LCM(72,21,43,802) = ( 72 × 21 × 43 × 802 ) / 6

LCM(72,21,43,802) = 52142832 / 6

LCM(72,21,43,802) = 8690472

∴ Least Common Multiple of 72,21,43,802 is 8690472
