Lets's calculate LCM of 691,370
Given numbers has no common factors except 1. So, there LCM is their product i.e 255670
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/255670
Therefore, the GCF of Fractions 680/691,939/370 is 1/255670
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 691,370 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(691,370) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(691,370) x common factors =1 x 1 = 1
LCM(691,370) = ( 691 × 370 ) / 1
LCM(691,370) = 255670 / 1
LCM(691,370) = 255670
