Least Common Multiple of 65, 77, 20, 65

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

• Least Common Multiple of 65, 77, 20, 65 by common division method
• Least Common Multiple of 65, 77, 20, 65 with GCF Formula

∴ So the LCM of the given numbers is 5 x 13 x 1 x 77 x 4 x 1 = 20020

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 65,77,20,65 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(65,77,20,65) = 1

common factors(in case of two or more numbers have common factors) = 325

GCF(65,77,20,65) x common factors =1 x 325 = 325

LCM(65,77,20,65) = ( 65 × 77 × 20 × 65 ) / 325

LCM(65,77,20,65) = 6506500 / 325

LCM(65,77,20,65) = 20020

∴ Least Common Multiple of 65,77,20,65 is 20020
