Greatest Common Factor
We found the factors 660,865 . The biggest common factor number is the GCF number.
So the greatest common factor 660,865 is 5.
Lets's calculate LCM of 911,409
Given numbers has no common factors except 1. So, there LCM is their product i.e 372599
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/372599
Therefore, the GCF of Fractions 660/911,865/409 is 5/372599
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 911,409 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(911,409) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(911,409) x common factors =1 x 1 = 1
LCM(911,409) = ( 911 × 409 ) / 1
LCM(911,409) = 372599 / 1
LCM(911,409) = 372599
