Greatest Common Factor
We found the factors 28,71,945 . The biggest common factor number is the GCF number.
So the greatest common factor 28,71,945 is 1.
Lets's calculate LCM of 71,86,759
Given numbers has no common factors except 1. So, there LCM is their product i.e 4634454
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4634454
Therefore, the GCF of Fractions 28/71,71/86,945/759 is 1/4634454
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 71,86,759 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,86,759) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,86,759) x common factors =1 x 1 = 1
LCM(71,86,759) = ( 71 × 86 × 759 ) / 1
LCM(71,86,759) = 4634454 / 1
LCM(71,86,759) = 4634454
Here are some samples of GCF of Fractions calculations.
