Use the LCM of two or more numbers Calculator to find the Least Common Multiple of numbers 6851, 7990 i.e. 3219970 smallest integer divisible by all numbers.
Least common multiple (LCM) of 6851, 7990 is 3219970.
LCM(6851, 7990) = 3219970
Least common multiple or lowest common denominator (lcd) can be calculated in three ways
17 | 6851, 7990 |
403, 470 |
∴ So the LCM of the given numbers is 17 x 403 x 470 = 3219970
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 6851,7990 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(6851,7990) = 17
common factors(in case of two or more numbers have common factors) = 1
GCF(6851,7990) x common factors =17 x 1 = 17
LCM(6851,7990) = ( 6851 × 7990 ) / 17
LCM(6851,7990) = 54739490 / 17
LCM(6851,7990) = 3219970
∴ Least Common Multiple of 6851,7990 is 3219970
