Lets's calculate LCM of 118,757
Given numbers has no common factors except 1. So, there LCM is their product i.e 89326
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/89326
Therefore, the GCF of Fractions 399/118,708/757 is 3/89326
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 118,757 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(118,757) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(118,757) x common factors =1 x 1 = 1
LCM(118,757) = ( 118 × 757 ) / 1
LCM(118,757) = 89326 / 1
LCM(118,757) = 89326
