So the greatest common factor 678,885 is 3.
Lets's calculate LCM of 149,312
Given numbers has no common factors except 1. So, there LCM is their product i.e 46488
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/46488
Therefore, the GCF of Fractions 678/149,885/312 is 3/46488
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 149,312 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(149,312) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(149,312) x common factors =1 x 1 = 1
LCM(149,312) = ( 149 × 312 ) / 1
LCM(149,312) = 46488 / 1
LCM(149,312) = 46488
