:1,2,7,14,29,58,203,406
Greatest Common Factor
We found the factors 570,406 . The biggest common factor number is the GCF number.
So the greatest common factor 570,406 is 2.
Lets's calculate LCM of 947,860
Given numbers has no common factors except 1. So, there LCM is their product i.e 814420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/814420
Therefore, the GCF of Fractions 570/947,406/860 is 2/814420
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 947,860 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(947,860) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(947,860) x common factors =1 x 1 = 1
LCM(947,860) = ( 947 × 860 ) / 1
LCM(947,860) = 814420 / 1
LCM(947,860) = 814420
