Greatest Common Factor
We found the factors 691,699 . The biggest common factor number is the GCF number.
So the greatest common factor 691,699 is 1.
Lets's calculate LCM of 872,661
Given numbers has no common factors except 1. So, there LCM is their product i.e 576392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/576392
Therefore, the GCF of Fractions 691/872,699/661 is 1/576392
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 872,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(872,661) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(872,661) x common factors =1 x 1 = 1
LCM(872,661) = ( 872 × 661 ) / 1
LCM(872,661) = 576392 / 1
LCM(872,661) = 576392
