Now, list down the factors of 771
:1,3,257,771
Now, list down the factors of 474
:1,2,3,6,79,158,237,474
Greatest Common Factor
We found the factors 771,474 . The biggest common factor number is the GCF number.
So the greatest common factor 771,474 is 3.
Lets's calculate LCM of 853,690
Given numbers has no common factors except 1. So, there LCM is their product i.e 588570
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/588570
Therefore, the GCF of Fractions 771/853,474/690 is 3/588570
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 853,690 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(853,690) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(853,690) x common factors =1 x 1 = 1
LCM(853,690) = ( 853 × 690 ) / 1
LCM(853,690) = 588570 / 1
LCM(853,690) = 588570
