:1,2,4,8,103,206,412,824
Greatest Common Factor
We found the factors 787,824 . The biggest common factor number is the GCF number.
So the greatest common factor 787,824 is 1.
Lets's calculate LCM of 820,157
Given numbers has no common factors except 1. So, there LCM is their product i.e 128740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/128740
Therefore, the GCF of Fractions 787/820,824/157 is 1/128740
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 820,157 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(820,157) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(820,157) x common factors =1 x 1 = 1
LCM(820,157) = ( 820 × 157 ) / 1
LCM(820,157) = 128740 / 1
LCM(820,157) = 128740
