So the greatest common factor 980,512 is 4.
Lets's calculate LCM of 717,938
Given numbers has no common factors except 1. So, there LCM is their product i.e 672546
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/672546
Therefore, the GCF of Fractions 980/717,512/938 is 4/672546
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 717,938 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(717,938) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(717,938) x common factors =1 x 1 = 1
LCM(717,938) = ( 717 × 938 ) / 1
LCM(717,938) = 672546 / 1
LCM(717,938) = 672546
