Least Common Multiple of 81, 73, 686

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

• Least Common Multiple of 81, 73, 686 by common division method
• Least Common Multiple of 81, 73, 686 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 4056318

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 81,73,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,73,686) = 1

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

GCF(81,73,686) x common factors =1 x 1 = 1

LCM(81,73,686) = ( 81 × 73 × 686 ) / 1

LCM(81,73,686) = 4056318 / 1

LCM(81,73,686) = 4056318

∴ Least Common Multiple of 81,73,686 is 4056318

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

• LCM of 52, 37, 472
• LCM of 30, 32, 797
• LCM of 46, 50, 701
• LCM of 42, 56, 458
• LCM of 95, 79, 493
