Greatest Common Factor
We found the factors 23,30,39,56 . The biggest common factor number is the GCF number.
So the greatest common factor 23,30,39,56 is 1.
Lets's calculate LCM of 78,83,35,933
3 | 78, 83, 35, 933 |
26, 83, 35, 311 |
∴ So the LCM of the given numbers is 3 x 26 x 83 x 35 x 311 = 70469490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/70469490
Therefore, the GCF of Fractions 23/78,30/83,39/35,56/933 is 1/70469490
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 78,83,35,933 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,83,35,933) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(78,83,35,933) x common factors =1 x 3 = 3
LCM(78,83,35,933) = ( 78 × 83 × 35 × 933 ) / 3
LCM(78,83,35,933) = 211408470 / 3
LCM(78,83,35,933) = 70469490
