Least Common Multiple of 640, 408, 560, 210

Q: How to Find the LCM of 640, 408, 560, 210 ?

Least Common Multiple of 640, 408, 560, 210 = 228480 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, 408, 560, 210) = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 7 x 17 = 228480.

Least Common Multiple of 640,408,560,210 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 640,408,560,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(640,408,560,210) = 2

common factors(in case of two or more numbers have common factors) = 67200

GCF(640,408,560,210) x common factors =2 x 67200 = 134400

LCM(640,408,560,210) = ( 640 × 408 × 560 × 210 ) / 134400

LCM(640,408,560,210) = 30707712000 / 134400

LCM(640,408,560,210) = 228480

∴ Least Common Multiple of 640,408,560,210 is 228480
