Least Common Multiple of 924, 220, 21

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

• Least Common Multiple of 924, 220, 21 by common division method
• Least Common Multiple of 924, 220, 21 with GCF Formula

∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 11 x 1 x 5 x 1 = 4620

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 924,220,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(924,220,21) = 1

common factors(in case of two or more numbers have common factors) = 924

GCF(924,220,21) x common factors =1 x 924 = 924

LCM(924,220,21) = ( 924 × 220 × 21 ) / 924

LCM(924,220,21) = 4268880 / 924

LCM(924,220,21) = 4620

∴ Least Common Multiple of 924,220,21 is 4620

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

• LCM of 632, 773, 29
• LCM of 560, 348, 16
• LCM of 981, 534, 72
• LCM of 548, 264, 58
