Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 756, 768, 280 i.e. 241920 smallest integer divisible by all numbers.
Least common multiple (LCM) of 756, 768, 280 is 241920.
LCM(756, 768, 280) = 241920
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 756, 768, 280 |
2 | 378, 384, 140 |
2 | 189, 192, 70 |
3 | 189, 96, 35 |
7 | 63, 32, 35 |
9, 32, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 7 x 9 x 32 x 5 = 241920
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 756,768,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(756,768,280) = 4
common factors(in case of two or more numbers have common factors) = 168
GCF(756,768,280) x common factors =4 x 168 = 672
LCM(756,768,280) = ( 756 × 768 × 280 ) / 672
LCM(756,768,280) = 162570240 / 672
LCM(756,768,280) = 241920
∴ Least Common Multiple of 756,768,280 is 241920
