Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 781, 3989 i.e. 3115409 smallest integer divisible by all numbers.
Least common multiple (LCM) of 781, 3989 is 3115409.
LCM(781, 3989) = 3115409
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
Given numbers has no common factors except 1. So, there LCM is their product i.e 3115409
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 781,3989 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(781,3989) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(781,3989) x common factors =1 x 1 = 1
LCM(781,3989) = ( 781 × 3989 ) / 1
LCM(781,3989) = 3115409 / 1
LCM(781,3989) = 3115409
∴ Least Common Multiple of 781,3989 is 3115409
