Least Common Multiple of 77, 187, 221

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

• Least Common Multiple of 77, 187, 221 by common division method
• Least Common Multiple of 77, 187, 221 with GCF Formula

∴ So the LCM of the given numbers is 11 x 17 x 7 x 1 x 13 = 17017

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 77,187,221 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,187,221) = 1

common factors(in case of two or more numbers have common factors) = 187

GCF(77,187,221) x common factors =1 x 187 = 187

LCM(77,187,221) = ( 77 × 187 × 221 ) / 187

LCM(77,187,221) = 3182179 / 187

LCM(77,187,221) = 17017

∴ Least Common Multiple of 77,187,221 is 17017

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

• LCM of 67, 285, 250
• LCM of 63, 228, 950
