Least Common Multiple of 40, 60, 78, 43 with GCF Formula

Least Common Multiple of 40,60,78,43

Least Common Multiple (LCM) of 40,60,78,43 is 67080

2	40, 60, 78, 43
2	20, 30, 39, 43
3	10, 15, 39, 43
5	10, 5, 13, 43
	2, 1, 13, 43

∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 2 x 1 x 13 x 43 = 67080

Least Common Multiple of 40,60,78,43 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 40,60,78,43 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(40,60,78,43) = 1

common factors(in case of two or more numbers have common factors) = 120

GCF(40,60,78,43) x common factors =1 x 120 = 120

LCM(40,60,78,43) = ( 40 × 60 × 78 × 43 ) / 120

LCM(40,60,78,43) = 8049600 / 120

LCM(40,60,78,43) = 67080

∴ Least Common Multiple of 40,60,78,43 is 67080
