Least Common Multiple of 640, 160, 202, 654

Q: How to Find the LCM of 640, 160, 202, 654 ?

Least Common Multiple of 640, 160, 202, 654 = 21137280 Step 1: Divide all the numbers with common prime numbers having remainder zero. Step 2: Then multiply all the prime factors with last row quotient of common division that is LCM(640, 160, 202, 654) = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 101 x 109 = 21137280.

∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 5 x 4 x 1 x 101 x 327 = 21137280

Least Common Multiple of 640,160,202,654 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 640,160,202,654 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(640,160,202,654) = 2

common factors(in case of two or more numbers have common factors) = 320

GCF(640,160,202,654) x common factors =2 x 320 = 640

LCM(640,160,202,654) = ( 640 × 160 × 202 × 654 ) / 640

LCM(640,160,202,654) = 13527859200 / 640

LCM(640,160,202,654) = 21137280

∴ Least Common Multiple of 640,160,202,654 is 21137280
