So the greatest common factor 581,434 is 7.
Lets's calculate LCM of 688,745
Given numbers has no common factors except 1. So, there LCM is their product i.e 512560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/512560
Therefore, the GCF of Fractions 581/688,434/745 is 7/512560
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 688,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,745) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(688,745) x common factors =1 x 1 = 1
LCM(688,745) = ( 688 × 745 ) / 1
LCM(688,745) = 512560 / 1
LCM(688,745) = 512560
