Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 90, 49, 60, 655 i.e. 1155420 smallest integer divisible by all numbers.
Least common multiple (LCM) of 90, 49, 60, 655 is 1155420.
LCM(90, 49, 60, 655) = 1155420
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
2 | 90, 49, 60, 655 |
3 | 45, 49, 30, 655 |
5 | 15, 49, 10, 655 |
3, 49, 2, 131 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 49 x 2 x 131 = 1155420
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 90,49,60,655 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,49,60,655) = 1
common factors(in case of two or more numbers have common factors) = 150
GCF(90,49,60,655) x common factors =1 x 150 = 150
LCM(90,49,60,655) = ( 90 × 49 × 60 × 655 ) / 150
LCM(90,49,60,655) = 173313000 / 150
LCM(90,49,60,655) = 1155420
∴ Least Common Multiple of 90,49,60,655 is 1155420
