Least Common Multiple of 86, 21, 11

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

• Least Common Multiple of 86, 21, 11 by common division method
• Least Common Multiple of 86, 21, 11 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 19866

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 86,21,11 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(86,21,11) = 1

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

GCF(86,21,11) x common factors =1 x 1 = 1

LCM(86,21,11) = ( 86 × 21 × 11 ) / 1

LCM(86,21,11) = 19866 / 1

LCM(86,21,11) = 19866

∴ Least Common Multiple of 86,21,11 is 19866

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

• LCM of 98, 72, 35
• LCM of 97, 93, 37
• LCM of 59, 48, 81
• LCM of 49, 44, 31
• LCM of 47, 92, 78
