Lets's calculate LCM of 977,696,785
Given numbers has no common factors except 1. So, there LCM is their product i.e 533793720
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/533793720
Therefore, the GCF of Fractions 43/977,513/696,721/785 is 1/533793720
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 977,696,785 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(977,696,785) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(977,696,785) x common factors =1 x 1 = 1
LCM(977,696,785) = ( 977 × 696 × 785 ) / 1
LCM(977,696,785) = 533793720 / 1
LCM(977,696,785) = 533793720
