Least Common Multiple of 81, 19, 121

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

• Least Common Multiple of 81, 19, 121 by common division method
• Least Common Multiple of 81, 19, 121 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 186219

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 81,19,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(81,19,121) = 1

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

GCF(81,19,121) x common factors =1 x 1 = 1

LCM(81,19,121) = ( 81 × 19 × 121 ) / 1

LCM(81,19,121) = 186219 / 1

LCM(81,19,121) = 186219

∴ Least Common Multiple of 81,19,121 is 186219

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

• LCM of 64, 40, 275
• LCM of 59, 22, 759
• LCM of 22, 85, 392
• LCM of 99, 50, 755
• LCM of 16, 46, 600
