Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 78, 538, 807 i.e. 20982 smallest integer divisible by all numbers.
Least common multiple (LCM) of 78, 538, 807 is 20982.
LCM(78, 538, 807) = 20982
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 78, 538, 807 |
3 | 39, 269, 807 |
269 | 13, 269, 269 |
13, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 269 x 13 x 1 x 1 = 20982
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 78,538,807 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,538,807) = 1
common factors(in case of two or more numbers have common factors) = 1614
GCF(78,538,807) x common factors =1 x 1614 = 1614
LCM(78,538,807) = ( 78 × 538 × 807 ) / 1614
LCM(78,538,807) = 33864948 / 1614
LCM(78,538,807) = 20982
∴ Least Common Multiple of 78,538,807 is 20982
