Least Common Multiple of 84, 31, 980

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

• Least Common Multiple of 84, 31, 980 by common division method
• Least Common Multiple of 84, 31, 980 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 7 x 3 x 31 x 35 = 91140

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 84,31,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(84,31,980) = 1

common factors(in case of two or more numbers have common factors) = 28

GCF(84,31,980) x common factors =1 x 28 = 28

LCM(84,31,980) = ( 84 × 31 × 980 ) / 28

LCM(84,31,980) = 2551920 / 28

LCM(84,31,980) = 91140

∴ Least Common Multiple of 84,31,980 is 91140

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

• LCM of 55, 62, 722
• LCM of 91, 69, 977
• LCM of 12, 36, 603
