So the greatest common factor 837,640 is 1.
Lets's calculate LCM of 642,413
Given numbers has no common factors except 1. So, there LCM is their product i.e 265146
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/265146
Therefore, the GCF of Fractions 837/642,640/413 is 1/265146
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 642,413 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,413) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(642,413) x common factors =1 x 1 = 1
LCM(642,413) = ( 642 × 413 ) / 1
LCM(642,413) = 265146 / 1
LCM(642,413) = 265146
