Least Common Multiple of 21, 438, 511

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

• Least Common Multiple of 21, 438, 511 by common division method
• Least Common Multiple of 21, 438, 511 with GCF Formula

∴ So the LCM of the given numbers is 3 x 7 x 73 x 1 x 2 x 1 = 3066

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 21,438,511 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,438,511) = 1

common factors(in case of two or more numbers have common factors) = 1533

GCF(21,438,511) x common factors =1 x 1533 = 1533

LCM(21,438,511) = ( 21 × 438 × 511 ) / 1533

LCM(21,438,511) = 4700178 / 1533

LCM(21,438,511) = 3066

∴ Least Common Multiple of 21,438,511 is 3066

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

• LCM of 67, 119, 587
• LCM of 93, 452, 204
