Least Common Multiple of 77, 21, 42, 386

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

• Least Common Multiple of 77, 21, 42, 386 by common division method
• Least Common Multiple of 77, 21, 42, 386 with GCF Formula

∴ So the LCM of the given numbers is 2 x 3 x 7 x 11 x 1 x 1 x 193 = 89166

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 77,21,42,386 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(77,21,42,386) = 1

common factors(in case of two or more numbers have common factors) = 294

GCF(77,21,42,386) x common factors =1 x 294 = 294

LCM(77,21,42,386) = ( 77 × 21 × 42 × 386 ) / 294

LCM(77,21,42,386) = 26214804 / 294

LCM(77,21,42,386) = 89166

∴ Least Common Multiple of 77,21,42,386 is 89166
