So the greatest common factor 863,420 is 1.
Lets's calculate LCM of 51,3515
Given numbers has no common factors except 1. So, there LCM is their product i.e 179265
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/179265
Therefore, the GCF of Fractions 863/51,420/3515 is 1/179265
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 51,3515 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,3515) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(51,3515) x common factors =1 x 1 = 1
LCM(51,3515) = ( 51 × 3515 ) / 1
LCM(51,3515) = 179265 / 1
LCM(51,3515) = 179265
