We found the factors 872,1530 . The biggest common factor number is the GCF number.
So the greatest common factor 872,1530 is 2.
Lets's calculate LCM of 680,413
Given numbers has no common factors except 1. So, there LCM is their product i.e 280840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/280840
Therefore, the GCF of Fractions 872/680,1530/413 is 2/280840
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 680,413 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(680,413) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(680,413) x common factors =1 x 1 = 1
LCM(680,413) = ( 680 × 413 ) / 1
LCM(680,413) = 280840 / 1
LCM(680,413) = 280840
