Greatest Common Factor
We found the factors 790,971 . The biggest common factor number is the GCF number.
So the greatest common factor 790,971 is 1.
Lets's calculate LCM of 921,745
Given numbers has no common factors except 1. So, there LCM is their product i.e 686145
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/686145
Therefore, the GCF of Fractions 790/921,971/745 is 1/686145
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 921,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(921,745) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(921,745) x common factors =1 x 1 = 1
LCM(921,745) = ( 921 × 745 ) / 1
LCM(921,745) = 686145 / 1
LCM(921,745) = 686145
