Greatest Common Factor
We found the factors 663,689 . The biggest common factor number is the GCF number.
So the greatest common factor 663,689 is 13.
Lets's calculate LCM of 852,611
Given numbers has no common factors except 1. So, there LCM is their product i.e 520572
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 13/520572
Therefore, the GCF of Fractions 663/852,689/611 is 13/520572
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 852,611 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(852,611) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(852,611) x common factors =1 x 1 = 1
LCM(852,611) = ( 852 × 611 ) / 1
LCM(852,611) = 520572 / 1
LCM(852,611) = 520572
