:1,3,5,15,61,183,305,915
Greatest Common Factor
We found the factors 65,90,915 . The biggest common factor number is the GCF number.
So the greatest common factor 65,90,915 is 5.
Lets's calculate LCM of 68,83,281
Given numbers has no common factors except 1. So, there LCM is their product i.e 1585964
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1585964
Therefore, the GCF of Fractions 65/68,90/83,915/281 is 5/1585964
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 68,83,281 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,83,281) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(68,83,281) x common factors =1 x 1 = 1
LCM(68,83,281) = ( 68 × 83 × 281 ) / 1
LCM(68,83,281) = 1585964 / 1
LCM(68,83,281) = 1585964
