Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 977, 643, 643 i.e. 628211 smallest integer divisible by all numbers.
Least common multiple (LCM) of 977, 643, 643 is 628211.
LCM(977, 643, 643) = 628211
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
643 | 977, 643, 643 |
977, 1, 1 |
∴ So the LCM of the given numbers is 643 x 977 x 1 x 1 = 628211
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 977,643,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(977,643,643) = 1
common factors(in case of two or more numbers have common factors) = 643
GCF(977,643,643) x common factors =1 x 643 = 643
LCM(977,643,643) = ( 977 × 643 × 643 ) / 643
LCM(977,643,643) = 403939673 / 643
LCM(977,643,643) = 628211
∴ Least Common Multiple of 977,643,643 is 628211
