So the greatest common factor 126,870 is 6.
Lets's calculate LCM of 841,790
Given numbers has no common factors except 1. So, there LCM is their product i.e 664390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 6/664390
Therefore, the GCF of Fractions 126/841,870/790 is 6/664390
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 841,790 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(841,790) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(841,790) x common factors =1 x 1 = 1
LCM(841,790) = ( 841 × 790 ) / 1
LCM(841,790) = 664390 / 1
LCM(841,790) = 664390
