Greatest Common Factor
We found the factors 311,304,688 . The biggest common factor number is the GCF number.
So the greatest common factor 311,304,688 is 1.
Lets's calculate LCM of 48,99,91
3 | 48, 99, 91 |
16, 33, 91 |
∴ So the LCM of the given numbers is 3 x 16 x 33 x 91 = 144144
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/144144
Therefore, the GCF of Fractions 311/48,304/99,688/91 is 1/144144
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 48,99,91 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(48,99,91) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(48,99,91) x common factors =1 x 3 = 3
LCM(48,99,91) = ( 48 × 99 × 91 ) / 3
LCM(48,99,91) = 432432 / 3
LCM(48,99,91) = 144144
