Lets's calculate LCM of 233,638
Given numbers has no common factors except 1. So, there LCM is their product i.e 148654
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/148654
Therefore, the GCF of Fractions 945/233,7651/638 is 7/148654
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 233,638 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(233,638) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(233,638) x common factors =1 x 1 = 1
LCM(233,638) = ( 233 × 638 ) / 1
LCM(233,638) = 148654 / 1
LCM(233,638) = 148654
