Lets's calculate LCM of 974,455
Given numbers has no common factors except 1. So, there LCM is their product i.e 443170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/443170
Therefore, the GCF of Fractions 992/974,688/455 is 16/443170
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 974,455 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(974,455) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(974,455) x common factors =1 x 1 = 1
LCM(974,455) = ( 974 × 455 ) / 1
LCM(974,455) = 443170 / 1
LCM(974,455) = 443170
