Greatest Common Factor
We found the factors 991,634 . The biggest common factor number is the GCF number.
So the greatest common factor 991,634 is 1.
Lets's calculate LCM of 623,653
Given numbers has no common factors except 1. So, there LCM is their product i.e 406819
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/406819
Therefore, the GCF of Fractions 991/623,634/653 is 1/406819
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 623,653 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(623,653) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(623,653) x common factors =1 x 1 = 1
LCM(623,653) = ( 623 × 653 ) / 1
LCM(623,653) = 406819 / 1
LCM(623,653) = 406819
