Least Common Multiple of 16, 81, 80, 55, 72

Q: How to Find the LCM of 16, 81, 80, 55, 72 ?

Least Common Multiple of 16, 81, 80, 55, 72 = 71280 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(16, 81, 80, 55, 72) = 2 x 2 x 2 x 2 x 3 x 3 x 3 x 3 x 5 x 11 = 71280.

Least Common Multiple of 16,81,80,55,72 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 16,81,80,55,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(16,81,80,55,72) = 1

common factors(in case of two or more numbers have common factors) = 5760

GCF(16,81,80,55,72) x common factors =1 x 5760 = 5760

LCM(16,81,80,55,72) = ( 16 × 81 × 80 × 55 × 72 ) / 5760

LCM(16,81,80,55,72) = 410572800 / 5760

LCM(16,81,80,55,72) = 71280

∴ Least Common Multiple of 16,81,80,55,72 is 71280
