So the greatest common factor 978,351 is 3.
Lets's calculate LCM of 999,782
Given numbers has no common factors except 1. So, there LCM is their product i.e 781218
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/781218
Therefore, the GCF of Fractions 978/999,351/782 is 3/781218
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 999,782 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(999,782) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(999,782) x common factors =1 x 1 = 1
LCM(999,782) = ( 999 × 782 ) / 1
LCM(999,782) = 781218 / 1
LCM(999,782) = 781218
