Lets's calculate LCM of 178,813
Given numbers has no common factors except 1. So, there LCM is their product i.e 144714
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/144714
Therefore, the GCF of Fractions 168/178,2211/813 is 3/144714
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 178,813 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(178,813) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(178,813) x common factors =1 x 1 = 1
LCM(178,813) = ( 178 × 813 ) / 1
LCM(178,813) = 144714 / 1
LCM(178,813) = 144714
Here are some samples of GCF of Fractions calculations.
