Least Common Multiple of 121, 220, 20

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

• Least Common Multiple of 121, 220, 20 by common division method
• Least Common Multiple of 121, 220, 20 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 5 x 11 x 1 x 11 x 1 = 2420

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 121,220,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(121,220,20) = 1

common factors(in case of two or more numbers have common factors) = 220

GCF(121,220,20) x common factors =1 x 220 = 220

LCM(121,220,20) = ( 121 × 220 × 20 ) / 220

LCM(121,220,20) = 532400 / 220

LCM(121,220,20) = 2420

∴ Least Common Multiple of 121,220,20 is 2420

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

• LCM of 886, 372, 82
• LCM of 358, 424, 63
• LCM of 543, 325, 95
• LCM of 256, 315, 62
