Greatest Common Factor
We found the factors 4,84,17 . The biggest common factor number is the GCF number.
So the greatest common factor 4,84,17 is 1.
Lets's calculate LCM of 87,425,686
Given numbers has no common factors except 1. So, there LCM is their product i.e 25364850
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/25364850
Therefore, the GCF of Fractions 4/87,84/425,17/686 is 1/25364850
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 87,425,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,425,686) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(87,425,686) x common factors =1 x 1 = 1
LCM(87,425,686) = ( 87 × 425 × 686 ) / 1
LCM(87,425,686) = 25364850 / 1
LCM(87,425,686) = 25364850
