Lets's calculate LCM of 615,9540
3 | 615, 9540 |
5 | 205, 3180 |
41, 636 |
∴ So the LCM of the given numbers is 3 x 5 x 41 x 636 = 391140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/391140
Therefore, the GCF of Fractions 308/615,9177/9540 is 7/391140
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 615,9540 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(615,9540) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(615,9540) x common factors =15 x 1 = 15
LCM(615,9540) = ( 615 × 9540 ) / 15
LCM(615,9540) = 5867100 / 15
LCM(615,9540) = 391140
