So the greatest common factor 945,138 is 3.
Lets's calculate LCM of 353,790
Given numbers has no common factors except 1. So, there LCM is their product i.e 278870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/278870
Therefore, the GCF of Fractions 945/353,138/790 is 3/278870
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 353,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(353,790) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(353,790) x common factors =1 x 1 = 1
LCM(353,790) = ( 353 × 790 ) / 1
LCM(353,790) = 278870 / 1
LCM(353,790) = 278870
