Least Common Multiple of 9991, 7809

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

• Least Common Multiple of 9991, 7809 by common division method
• Least Common Multiple of 9991, 7809 with GCF Formula

Given numbers has no common factors except 1. So, there LCM is their product i.e 78019719

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 9991,7809 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(9991,7809) = 1

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

GCF(9991,7809) x common factors =1 x 1 = 1

LCM(9991,7809) = ( 9991 × 7809 ) / 1

LCM(9991,7809) = 78019719 / 1

LCM(9991,7809) = 78019719

∴ Least Common Multiple of 9991,7809 is 78019719

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

• LCM of 6088, 1823
• LCM of 9183, 5925
