Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 75, 45, 639 i.e. 15975 smallest integer divisible by all numbers.
Least common multiple (LCM) of 75, 45, 639 is 15975.
LCM(75, 45, 639) = 15975
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
3 | 75, 45, 639 |
3 | 25, 15, 213 |
5 | 25, 5, 71 |
1, 5, 71 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 1 x 5 x 71 = 15975
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 75,45,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(75,45,639) = 3
common factors(in case of two or more numbers have common factors) = 45
GCF(75,45,639) x common factors =3 x 45 = 135
LCM(75,45,639) = ( 75 × 45 × 639 ) / 135
LCM(75,45,639) = 2156625 / 135
LCM(75,45,639) = 15975
∴ Least Common Multiple of 75,45,639 is 15975
