So the greatest common factor 49,858,943 is 1.
Lets's calculate LCM of 68,47,785
Given numbers has no common factors except 1. So, there LCM is their product i.e 2508860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2508860
Therefore, the GCF of Fractions 49/68,858/47,943/785 is 1/2508860
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 68,47,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,47,785) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(68,47,785) x common factors =1 x 1 = 1
LCM(68,47,785) = ( 68 × 47 × 785 ) / 1
LCM(68,47,785) = 2508860 / 1
LCM(68,47,785) = 2508860
