Greatest Common Factor
We found the factors 234,867 . The biggest common factor number is the GCF number.
So the greatest common factor 234,867 is 3.
Lets's calculate LCM of 385,480
5 | 385, 480 |
77, 96 |
∴ So the LCM of the given numbers is 5 x 77 x 96 = 36960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/36960
Therefore, the GCF of Fractions 234/385,867/480 is 3/36960
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 385,480 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(385,480) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(385,480) x common factors =5 x 1 = 5
LCM(385,480) = ( 385 × 480 ) / 5
LCM(385,480) = 184800 / 5
LCM(385,480) = 36960
