Least Common Multiple of 21, 61, 854

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

• Least Common Multiple of 21, 61, 854 by common division method
• Least Common Multiple of 21, 61, 854 with GCF Formula

∴ So the LCM of the given numbers is 7 x 61 x 3 x 1 x 2 = 2562

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 21,61,854 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,61,854) = 1

common factors(in case of two or more numbers have common factors) = 427

GCF(21,61,854) x common factors =1 x 427 = 427

LCM(21,61,854) = ( 21 × 61 × 854 ) / 427

LCM(21,61,854) = 1093974 / 427

LCM(21,61,854) = 2562

∴ Least Common Multiple of 21,61,854 is 2562

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

• LCM of 62, 61, 272
• LCM of 67, 23, 687
