Greatest Common Factor
We found the factors 858,3900 . The biggest common factor number is the GCF number.
So the greatest common factor 858,3900 is 78.
Lets's calculate LCM of 396,1427
Given numbers has no common factors except 1. So, there LCM is their product i.e 565092
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 78/565092
Therefore, the GCF of Fractions 858/396,3900/1427 is 78/565092
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 396,1427 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(396,1427) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(396,1427) x common factors =1 x 1 = 1
LCM(396,1427) = ( 396 × 1427 ) / 1
LCM(396,1427) = 565092 / 1
LCM(396,1427) = 565092
