Lets's calculate LCM of 991,824
Given numbers has no common factors except 1. So, there LCM is their product i.e 816584
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/816584
Therefore, the GCF of Fractions 616/991,642/824 is 2/816584
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 991,824 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(991,824) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(991,824) x common factors =1 x 1 = 1
LCM(991,824) = ( 991 × 824 ) / 1
LCM(991,824) = 816584 / 1
LCM(991,824) = 816584
