Greatest Common Factor
We found the factors 647,453 . The biggest common factor number is the GCF number.
So the greatest common factor 647,453 is 1.
Lets's calculate LCM of 912,955
Given numbers has no common factors except 1. So, there LCM is their product i.e 870960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/870960
Therefore, the GCF of Fractions 647/912,453/955 is 1/870960
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 912,955 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(912,955) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(912,955) x common factors =1 x 1 = 1
LCM(912,955) = ( 912 × 955 ) / 1
LCM(912,955) = 870960 / 1
LCM(912,955) = 870960
