So the greatest common factor 748,657 is 1.
Lets's calculate LCM of 458,646
2 | 458, 646 |
229, 323 |
∴ So the LCM of the given numbers is 2 x 229 x 323 = 147934
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/147934
Therefore, the GCF of Fractions 748/458,657/646 is 1/147934
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 458,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(458,646) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(458,646) x common factors =2 x 1 = 2
LCM(458,646) = ( 458 × 646 ) / 2
LCM(458,646) = 295868 / 2
LCM(458,646) = 147934
