Greatest Common Factor
We found the factors 770,842 . The biggest common factor number is the GCF number.
So the greatest common factor 770,842 is 2.
Lets's calculate LCM of 72,769
Given numbers has no common factors except 1. So, there LCM is their product i.e 55368
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/55368
Therefore, the GCF of Fractions 770/72,842/769 is 2/55368
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 72,769 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,769) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(72,769) x common factors =1 x 1 = 1
LCM(72,769) = ( 72 × 769 ) / 1
LCM(72,769) = 55368 / 1
LCM(72,769) = 55368
