Greatest Common Factor
We found the factors 817,589,273 . The biggest common factor number is the GCF number.
So the greatest common factor 817,589,273 is 1.
Lets's calculate LCM of 74,43,40
2 | 74, 43, 40 |
37, 43, 20 |
∴ So the LCM of the given numbers is 2 x 37 x 43 x 20 = 63640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/63640
Therefore, the GCF of Fractions 817/74,589/43,273/40 is 1/63640
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 74,43,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,43,40) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(74,43,40) x common factors =1 x 2 = 2
LCM(74,43,40) = ( 74 × 43 × 40 ) / 2
LCM(74,43,40) = 127280 / 2
LCM(74,43,40) = 63640
