:1,3,7,19,21,57,133,399
Greatest Common Factor
We found the factors 435,399 . The biggest common factor number is the GCF number.
So the greatest common factor 435,399 is 3.
Lets's calculate LCM of 231,785
Given numbers has no common factors except 1. So, there LCM is their product i.e 181335
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/181335
Therefore, the GCF of Fractions 435/231,399/785 is 3/181335
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 231,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(231,785) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(231,785) x common factors =1 x 1 = 1
LCM(231,785) = ( 231 × 785 ) / 1
LCM(231,785) = 181335 / 1
LCM(231,785) = 181335
