Least Common Multiple of 53,40,646

Least Common Multiple (LCM) of 53,40,646 is 684760

2	53, 40, 646
	53, 20, 323

∴ So the LCM of the given numbers is 2 x 53 x 20 x 323 = 684760

Least Common Multiple of 53,40,646 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 53,40,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(53,40,646) = 1

common factors(in case of two or more numbers have common factors) = 2

GCF(53,40,646) x common factors =1 x 2 = 2

LCM(53,40,646) = ( 53 × 40 × 646 ) / 2

LCM(53,40,646) = 1369520 / 2

LCM(53,40,646) = 684760

∴ Least Common Multiple of 53,40,646 is 684760
