Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 7800, 3960 i.e. 257400 smallest integer divisible by all numbers.
Least common multiple (LCM) of 7800, 3960 is 257400.
LCM(7800, 3960) = 257400
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 7800, 3960 |
2 | 3900, 1980 |
2 | 1950, 990 |
3 | 975, 495 |
5 | 325, 165 |
65, 33 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 5 x 65 x 33 = 257400
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 7800,3960 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7800,3960) = 120
common factors(in case of two or more numbers have common factors) = 1
GCF(7800,3960) x common factors =120 x 1 = 120
LCM(7800,3960) = ( 7800 × 3960 ) / 120
LCM(7800,3960) = 30888000 / 120
LCM(7800,3960) = 257400
∴ Least Common Multiple of 7800,3960 is 257400
