Least Common Multiple of 31, 138

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

• Least Common Multiple of 31, 138 by common division method
• Least Common Multiple of 31, 138 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 4278

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 31,138 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(31,138) = 1

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

GCF(31,138) x common factors =1 x 1 = 1

LCM(31,138) = ( 31 × 138 ) / 1

LCM(31,138) = 4278 / 1

LCM(31,138) = 4278

∴ Least Common Multiple of 31,138 is 4278

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

• LCM of 11, 507
• LCM of 59, 537
• LCM of 75, 725
• LCM of 29, 153
• LCM of 94, 122

3. How to Find the LCM of 31, 138 ?

Least Common Multiple of 31, 138.

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(31, 138) = 2 x 3 x 23 x 31 = 4278.
