Least Common Multiple of 921, 1220

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

• Least Common Multiple of 921, 1220 by common division method
• Least Common Multiple of 921, 1220 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 1123620

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 921,1220 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(921,1220) = 1

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

GCF(921,1220) x common factors =1 x 1 = 1

LCM(921,1220) = ( 921 × 1220 ) / 1

LCM(921,1220) = 1123620 / 1

LCM(921,1220) = 1123620

∴ Least Common Multiple of 921,1220 is 1123620

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

• LCM of 737, 4421
• LCM of 140, 9077
• LCM of 346, 1994
• LCM of 426, 6273
• LCM of 174, 1045
