Least Common Multiple of 17, 21, 421

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

• Least Common Multiple of 17, 21, 421 by common division method
• Least Common Multiple of 17, 21, 421 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 150297

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 17,21,421 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(17,21,421) = 1

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

GCF(17,21,421) x common factors =1 x 1 = 1

LCM(17,21,421) = ( 17 × 21 × 421 ) / 1

LCM(17,21,421) = 150297 / 1

LCM(17,21,421) = 150297

∴ Least Common Multiple of 17,21,421 is 150297

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

• LCM of 18, 96, 680
• LCM of 85, 20, 105
• LCM of 82, 55, 127
• LCM of 37, 76, 958
• LCM of 12, 39, 136
