Least Common Multiple of 21, 17, 197

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

• Least Common Multiple of 21, 17, 197 by common division method
• Least Common Multiple of 21, 17, 197 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 70329

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 21,17,197 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(21,17,197) = 1

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

GCF(21,17,197) x common factors =1 x 1 = 1

LCM(21,17,197) = ( 21 × 17 × 197 ) / 1

LCM(21,17,197) = 70329 / 1

LCM(21,17,197) = 70329

∴ Least Common Multiple of 21,17,197 is 70329

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

• LCM of 62, 24, 403
• LCM of 94, 46, 765
• LCM of 14, 50, 895
• LCM of 22, 27, 158
• LCM of 46, 49, 744
