Lets's calculate LCM of 655,491
Given numbers has no common factors except 1. So, there LCM is their product i.e 321605
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/321605
Therefore, the GCF of Fractions 785/655,875/491 is 5/321605
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 655,491 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(655,491) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(655,491) x common factors =1 x 1 = 1
LCM(655,491) = ( 655 × 491 ) / 1
LCM(655,491) = 321605 / 1
LCM(655,491) = 321605
