Greatest Common Factor
We found the factors 902,809 . The biggest common factor number is the GCF number.
So the greatest common factor 902,809 is 1.
Lets's calculate LCM of 709,407
Given numbers has no common factors except 1. So, there LCM is their product i.e 288563
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/288563
Therefore, the GCF of Fractions 902/709,809/407 is 1/288563
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 709,407 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(709,407) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(709,407) x common factors =1 x 1 = 1
LCM(709,407) = ( 709 × 407 ) / 1
LCM(709,407) = 288563 / 1
LCM(709,407) = 288563
