:1,7901
Greatest Common Factor
We found the factors 1170,7901 . The biggest common factor number is the GCF number.
So the greatest common factor 1170,7901 is 1.
Lets's calculate LCM of 639,647
Given numbers has no common factors except 1. So, there LCM is their product i.e 413433
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/413433
Therefore, the GCF of Fractions 1170/639,7901/647 is 1/413433
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 639,647 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(639,647) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(639,647) x common factors =1 x 1 = 1
LCM(639,647) = ( 639 × 647 ) / 1
LCM(639,647) = 413433 / 1
LCM(639,647) = 413433
