Greatest Common Factor
We found the factors 728,138,690 . The biggest common factor number is the GCF number.
So the greatest common factor 728,138,690 is 2.
Lets's calculate LCM of 87,11,367
Given numbers has no common factors except 1. So, there LCM is their product i.e 351219
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/351219
Therefore, the GCF of Fractions 728/87,138/11,690/367 is 2/351219
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 87,11,367 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,11,367) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(87,11,367) x common factors =1 x 1 = 1
LCM(87,11,367) = ( 87 × 11 × 367 ) / 1
LCM(87,11,367) = 351219 / 1
LCM(87,11,367) = 351219
