Least Common Multiple of 31, 61, 381

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

• Least Common Multiple of 31, 61, 381 by common division method
• Least Common Multiple of 31, 61, 381 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 720471

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 31,61,381 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,61,381) = 1

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

GCF(31,61,381) x common factors =1 x 1 = 1

LCM(31,61,381) = ( 31 × 61 × 381 ) / 1

LCM(31,61,381) = 720471 / 1

LCM(31,61,381) = 720471

∴ Least Common Multiple of 31,61,381 is 720471

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

• LCM of 67, 89, 906
• LCM of 71, 96, 755
• LCM of 40, 70, 228
• LCM of 17, 77, 724
• LCM of 10, 30, 580
