So the greatest common factor 108,909 is 9.
Lets's calculate LCM of 245,435
5 | 245, 435 |
49, 87 |
∴ So the LCM of the given numbers is 5 x 49 x 87 = 21315
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 9/21315
Therefore, the GCF of Fractions 108/245,909/435 is 9/21315
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 245,435 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(245,435) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(245,435) x common factors =5 x 1 = 5
LCM(245,435) = ( 245 × 435 ) / 5
LCM(245,435) = 106575 / 5
LCM(245,435) = 21315
