Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 76, 65, 56, 720 i.e. 1244880 smallest integer divisible by all numbers.
Least common multiple (LCM) of 76, 65, 56, 720 is 1244880.
LCM(76, 65, 56, 720) = 1244880
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 76, 65, 56, 720 |
2 | 38, 65, 28, 360 |
2 | 19, 65, 14, 180 |
5 | 19, 65, 7, 90 |
19, 13, 7, 18 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 19 x 13 x 7 x 18 = 1244880
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 76,65,56,720 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,65,56,720) = 1
common factors(in case of two or more numbers have common factors) = 160
GCF(76,65,56,720) x common factors =1 x 160 = 160
LCM(76,65,56,720) = ( 76 × 65 × 56 × 720 ) / 160
LCM(76,65,56,720) = 199180800 / 160
LCM(76,65,56,720) = 1244880
∴ Least Common Multiple of 76,65,56,720 is 1244880
