Lets's calculate LCM of 195,6411
3 | 195, 6411 |
65, 2137 |
∴ So the LCM of the given numbers is 3 x 65 x 2137 = 416715
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/416715
Therefore, the GCF of Fractions 1980/195,5540/6411 is 20/416715
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 195,6411 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(195,6411) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(195,6411) x common factors =3 x 1 = 3
LCM(195,6411) = ( 195 × 6411 ) / 3
LCM(195,6411) = 1250145 / 3
LCM(195,6411) = 416715
