Least Common Multiple of 43,40,64,80

Least Common Multiple (LCM) of 43,40,64,80 is 13760

2	43, 40, 64, 80
2	43, 20, 32, 40
2	43, 10, 16, 20
2	43, 5, 8, 10
5	43, 5, 4, 5
	43, 1, 4, 1

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 43 x 1 x 4 x 1 = 13760

Least Common Multiple of 43,40,64,80 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 43,40,64,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(43,40,64,80) = 1

common factors(in case of two or more numbers have common factors) = 640

GCF(43,40,64,80) x common factors =1 x 640 = 640

LCM(43,40,64,80) = ( 43 × 40 × 64 × 80 ) / 640

LCM(43,40,64,80) = 8806400 / 640

LCM(43,40,64,80) = 13760

∴ Least Common Multiple of 43,40,64,80 is 13760
