Lets's calculate LCM of 989,928
Given numbers has no common factors except 1. So, there LCM is their product i.e 917792
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/917792
Therefore, the GCF of Fractions 917/989,432/928 is 1/917792
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 989,928 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(989,928) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(989,928) x common factors =1 x 1 = 1
LCM(989,928) = ( 989 × 928 ) / 1
LCM(989,928) = 917792 / 1
LCM(989,928) = 917792
