Least Common Multiple of 81, 61, 139

Least common multiple or lowest common denominator (lcd) can be calculated in three ways

• Least Common Multiple of 81, 61, 139 by common division method
• Least Common Multiple of 81, 61, 139 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 686799

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 81,61,139 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,61,139) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(81,61,139) x common factors =1 x 1 = 1

LCM(81,61,139) = ( 81 × 61 × 139 ) / 1

LCM(81,61,139) = 686799 / 1

LCM(81,61,139) = 686799

∴ Least Common Multiple of 81,61,139 is 686799

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 54, 52, 804
• LCM of 19, 99, 503
• LCM of 95, 11, 641
• LCM of 65, 80, 980
• LCM of 92, 48, 433
