Greatest Common Factor
We found the factors 880,392,888 . The biggest common factor number is the GCF number.
So the greatest common factor 880,392,888 is 8.
Lets's calculate LCM of 61,77,289
Given numbers has no common factors except 1. So, there LCM is their product i.e 1357433
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/1357433
Therefore, the GCF of Fractions 880/61,392/77,888/289 is 8/1357433
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 61,77,289 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,77,289) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,77,289) x common factors =1 x 1 = 1
LCM(61,77,289) = ( 61 × 77 × 289 ) / 1
LCM(61,77,289) = 1357433 / 1
LCM(61,77,289) = 1357433
