Least Common Multiple of 91, 35, 20

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

• Least Common Multiple of 91, 35, 20 by common division method
• Least Common Multiple of 91, 35, 20 with GCF Formula

∴ So the LCM of the given numbers is 5 x 7 x 13 x 1 x 4 = 1820

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 91,35,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(91,35,20) = 1

common factors(in case of two or more numbers have common factors) = 35

GCF(91,35,20) x common factors =1 x 35 = 35

LCM(91,35,20) = ( 91 × 35 × 20 ) / 35

LCM(91,35,20) = 63700 / 35

LCM(91,35,20) = 1820

∴ Least Common Multiple of 91,35,20 is 1820

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

• LCM of 18, 73, 86
• LCM of 95, 56, 99
• LCM of 10, 89, 52
• LCM of 73, 48, 31
• LCM of 31, 94, 28
