Lets's calculate LCM of 688,769
Given numbers has no common factors except 1. So, there LCM is their product i.e 529072
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/529072
Therefore, the GCF of Fractions 988/688,3905/769 is 1/529072
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 688,769 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,769) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(688,769) x common factors =1 x 1 = 1
LCM(688,769) = ( 688 × 769 ) / 1
LCM(688,769) = 529072 / 1
LCM(688,769) = 529072
