Greatest Common Factor
We found the factors 157,159 . The biggest common factor number is the GCF number.
So the greatest common factor 157,159 is 1.
Lets's calculate LCM of 649,431
Given numbers has no common factors except 1. So, there LCM is their product i.e 279719
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/279719
Therefore, the GCF of Fractions 157/649,159/431 is 1/279719
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 649,431 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(649,431) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(649,431) x common factors =1 x 1 = 1
LCM(649,431) = ( 649 × 431 ) / 1
LCM(649,431) = 279719 / 1
LCM(649,431) = 279719
