So the greatest common factor 445,770 is 5.
Lets's calculate LCM of 751,938
Given numbers has no common factors except 1. So, there LCM is their product i.e 704438
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/704438
Therefore, the GCF of Fractions 445/751,770/938 is 5/704438
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 751,938 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(751,938) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(751,938) x common factors =1 x 1 = 1
LCM(751,938) = ( 751 × 938 ) / 1
LCM(751,938) = 704438 / 1
LCM(751,938) = 704438
