So the greatest common factor 826,870 is 2.
Lets's calculate LCM of 411,215
Given numbers has no common factors except 1. So, there LCM is their product i.e 88365
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/88365
Therefore, the GCF of Fractions 826/411,870/215 is 2/88365
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 411,215 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(411,215) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(411,215) x common factors =1 x 1 = 1
LCM(411,215) = ( 411 × 215 ) / 1
LCM(411,215) = 88365 / 1
LCM(411,215) = 88365
