Least Common Multiple of 86, 30, 78, 640

Q: How to Find the LCM of 86, 30, 78, 640 ?

Least Common Multiple of 86, 30, 78, 640 = 1073280 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(86, 30, 78, 640) = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 13 x 43 = 1073280.

Least Common Multiple of 86,30,78,640 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 86,30,78,640 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(86,30,78,640) = 2

common factors(in case of two or more numbers have common factors) = 60

GCF(86,30,78,640) x common factors =2 x 60 = 120

LCM(86,30,78,640) = ( 86 × 30 × 78 × 640 ) / 120

LCM(86,30,78,640) = 128793600 / 120

LCM(86,30,78,640) = 1073280

∴ Least Common Multiple of 86,30,78,640 is 1073280
