Greatest Common Factor
We found the factors 642,838,897 . The biggest common factor number is the GCF number.
So the greatest common factor 642,838,897 is 1.
Lets's calculate LCM of 71,10,973
Given numbers has no common factors except 1. So, there LCM is their product i.e 690830
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/690830
Therefore, the GCF of Fractions 642/71,838/10,897/973 is 1/690830
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 71,10,973 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,10,973) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(71,10,973) x common factors =1 x 1 = 1
LCM(71,10,973) = ( 71 × 10 × 973 ) / 1
LCM(71,10,973) = 690830 / 1
LCM(71,10,973) = 690830
Here are some samples of GCF of Fractions calculations.
