Lets's calculate LCM of 645,956
Given numbers has no common factors except 1. So, there LCM is their product i.e 616620
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/616620
Therefore, the GCF of Fractions 863/645,790/956 is 1/616620
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 645,956 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(645,956) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(645,956) x common factors =1 x 1 = 1
LCM(645,956) = ( 645 × 956 ) / 1
LCM(645,956) = 616620 / 1
LCM(645,956) = 616620
