Least Common Multiple of 21, 2728

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

• Least Common Multiple of 21, 2728 by common division method
• Least Common Multiple of 21, 2728 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 57288

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 21,2728 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,2728) = 1

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

GCF(21,2728) x common factors =1 x 1 = 1

LCM(21,2728) = ( 21 × 2728 ) / 1

LCM(21,2728) = 57288 / 1

LCM(21,2728) = 57288

∴ Least Common Multiple of 21,2728 is 57288

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

• LCM of 84, 3177
• LCM of 31, 8656
• LCM of 24, 3969
• LCM of 61, 5505
