:1,673
Greatest Common Factor
We found the factors 639,673 . The biggest common factor number is the GCF number.
So the greatest common factor 639,673 is 1.
Lets's calculate LCM of 652,705
Given numbers has no common factors except 1. So, there LCM is their product i.e 459660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/459660
Therefore, the GCF of Fractions 639/652,673/705 is 1/459660
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 652,705 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(652,705) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(652,705) x common factors =1 x 1 = 1
LCM(652,705) = ( 652 × 705 ) / 1
LCM(652,705) = 459660 / 1
LCM(652,705) = 459660
