Least Common Multiple of 53, 97, 21

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

• Least Common Multiple of 53, 97, 21 by common division method
• Least Common Multiple of 53, 97, 21 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 107961

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 53,97,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(53,97,21) = 1

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

GCF(53,97,21) x common factors =1 x 1 = 1

LCM(53,97,21) = ( 53 × 97 × 21 ) / 1

LCM(53,97,21) = 107961 / 1

LCM(53,97,21) = 107961

∴ Least Common Multiple of 53,97,21 is 107961

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

• LCM of 71, 45, 49
• LCM of 19, 84, 33
• LCM of 13, 38, 75
• LCM of 78, 65, 75
• LCM of 49, 54, 36
