Greatest Common Factor
We found the factors 786,426,847 . The biggest common factor number is the GCF number.
So the greatest common factor 786,426,847 is 1.
Lets's calculate LCM of 40,81,380
2 | 40, 81, 380 |
2 | 20, 81, 190 |
5 | 10, 81, 95 |
2, 81, 19 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 2 x 81 x 19 = 61560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/61560
Therefore, the GCF of Fractions 786/40,426/81,847/380 is 1/61560
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 40,81,380 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,81,380) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(40,81,380) x common factors =1 x 20 = 20
LCM(40,81,380) = ( 40 × 81 × 380 ) / 20
LCM(40,81,380) = 1231200 / 20
LCM(40,81,380) = 61560
