Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 70, 49, 643 i.e. 315070 smallest integer divisible by all numbers.
Least common multiple (LCM) of 70, 49, 643 is 315070.
LCM(70, 49, 643) = 315070
LCM of 70, 49, 643
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
- Least Common Multiple of 70, 49, 643 by common division method
- Least Common Multiple of 70, 49, 643 with GCF Formula
Least Common Multiple (LCM) of 70,49,643 is 315070
| 7 | 70, 49, 643 |
| 10, 7, 643 |
∴ So the LCM of the given numbers is 7 x 10 x 7 x 643 = 315070
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 70,49,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,49,643) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(70,49,643) x common factors =1 x 7 = 7
LCM(70,49,643) = ( 70 × 49 × 643 ) / 7
LCM(70,49,643) = 2205490 / 7
LCM(70,49,643) = 315070
∴ Least Common Multiple of 70,49,643 is 315070
