Lets's calculate LCM of 837,947
Given numbers has no common factors except 1. So, there LCM is their product i.e 792639
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/792639
Therefore, the GCF of Fractions 394/837,812/947 is 2/792639
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 837,947 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(837,947) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(837,947) x common factors =1 x 1 = 1
LCM(837,947) = ( 837 × 947 ) / 1
LCM(837,947) = 792639 / 1
LCM(837,947) = 792639
