Lets's calculate LCM of 175,417
Given numbers has no common factors except 1. So, there LCM is their product i.e 72975
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 21/72975
Therefore, the GCF of Fractions 903/175,7749/417 is 21/72975
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 175,417 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(175,417) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(175,417) x common factors =1 x 1 = 1
LCM(175,417) = ( 175 × 417 ) / 1
LCM(175,417) = 72975 / 1
LCM(175,417) = 72975
