Least Common Multiple of 69, 10, 31

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

• Least Common Multiple of 69, 10, 31 by common division method
• Least Common Multiple of 69, 10, 31 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 21390

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 69,10,31 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(69,10,31) = 1

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

GCF(69,10,31) x common factors =1 x 1 = 1

LCM(69,10,31) = ( 69 × 10 × 31 ) / 1

LCM(69,10,31) = 21390 / 1

LCM(69,10,31) = 21390

∴ Least Common Multiple of 69,10,31 is 21390

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

• LCM of 16, 14, 73
• LCM of 77, 43, 34
• LCM of 50, 44, 86
• LCM of 13, 92, 34
• LCM of 20, 61, 38
