Greatest Common Factor
We found the factors 207,493 . The biggest common factor number is the GCF number.
So the greatest common factor 207,493 is 1.
Lets's calculate LCM of 797,147
Given numbers has no common factors except 1. So, there LCM is their product i.e 117159
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/117159
Therefore, the GCF of Fractions 207/797,493/147 is 1/117159
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 797,147 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(797,147) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(797,147) x common factors =1 x 1 = 1
LCM(797,147) = ( 797 × 147 ) / 1
LCM(797,147) = 117159 / 1
LCM(797,147) = 117159
