So the greatest common factor 770,685 is 5.
Lets's calculate LCM of 545,162
Given numbers has no common factors except 1. So, there LCM is their product i.e 88290
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/88290
Therefore, the GCF of Fractions 770/545,685/162 is 5/88290
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 545,162 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(545,162) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(545,162) x common factors =1 x 1 = 1
LCM(545,162) = ( 545 × 162 ) / 1
LCM(545,162) = 88290 / 1
LCM(545,162) = 88290
