So the greatest common factor 25,20,855 is 5.
Lets's calculate LCM of 622,385,395
5 | 622, 385, 395 |
622, 77, 79 |
∴ So the LCM of the given numbers is 5 x 622 x 77 x 79 = 18918130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/18918130
Therefore, the GCF of Fractions 25/622,20/385,855/395 is 5/18918130
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 622,385,395 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(622,385,395) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(622,385,395) x common factors =1 x 5 = 5
LCM(622,385,395) = ( 622 × 385 × 395 ) / 5
LCM(622,385,395) = 94590650 / 5
LCM(622,385,395) = 18918130
