Lets's calculate LCM of 909,746
Given numbers has no common factors except 1. So, there LCM is their product i.e 678114
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/678114
Therefore, the GCF of Fractions 688/909,665/746 is 1/678114
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 909,746 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(909,746) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(909,746) x common factors =1 x 1 = 1
LCM(909,746) = ( 909 × 746 ) / 1
LCM(909,746) = 678114 / 1
LCM(909,746) = 678114
