Least Common Multiple of 31, 81, 421

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

• Least Common Multiple of 31, 81, 421 by common division method
• Least Common Multiple of 31, 81, 421 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1057131

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 31,81,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,81,421) = 1

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

GCF(31,81,421) x common factors =1 x 1 = 1

LCM(31,81,421) = ( 31 × 81 × 421 ) / 1

LCM(31,81,421) = 1057131 / 1

LCM(31,81,421) = 1057131

∴ Least Common Multiple of 31,81,421 is 1057131

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

• LCM of 83, 48, 311
• LCM of 46, 12, 437
• LCM of 47, 98, 859
• LCM of 53, 21, 223
• LCM of 12, 85, 236
