Least Common Multiple of 20, 457

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

• Least Common Multiple of 20, 457 by common division method
• Least Common Multiple of 20, 457 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 9140

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 20,457 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(20,457) = 1

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

GCF(20,457) x common factors =1 x 1 = 1

LCM(20,457) = ( 20 × 457 ) / 1

LCM(20,457) = 9140 / 1

LCM(20,457) = 9140

∴ Least Common Multiple of 20,457 is 9140

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

• LCM of 96, 938
• LCM of 92, 990
• LCM of 44, 840
• LCM of 28, 272
• LCM of 55, 180

3. How to Find the LCM of 20, 457 ?

Least Common Multiple of 20, 457.

Step 1: Divide all the numbers with common prime numbers having remainder zero.

Step 2: Then multiply all the prime factors with last row quotient of common division that is LCM(20, 457) = 2 x 2 x 5 x 457 = 9140.
