Greatest Common Factor
We found the factors 38,20,382 . The biggest common factor number is the GCF number.
So the greatest common factor 38,20,382 is 2.
Lets's calculate LCM of 765,751,355
5 | 765, 751, 355 |
153, 751, 71 |
∴ So the LCM of the given numbers is 5 x 153 x 751 x 71 = 40790565
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/40790565
Therefore, the GCF of Fractions 38/765,20/751,382/355 is 2/40790565
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 765,751,355 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(765,751,355) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(765,751,355) x common factors =1 x 5 = 5
LCM(765,751,355) = ( 765 × 751 × 355 ) / 5
LCM(765,751,355) = 203952825 / 5
LCM(765,751,355) = 40790565
