Greatest Common Factor
We found the factors 809,313,957 . The biggest common factor number is the GCF number.
So the greatest common factor 809,313,957 is 1.
Lets's calculate LCM of 30,40,77
2 | 30, 40, 77 |
5 | 15, 20, 77 |
3, 4, 77 |
∴ So the LCM of the given numbers is 2 x 5 x 3 x 4 x 77 = 9240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9240
Therefore, the GCF of Fractions 809/30,313/40,957/77 is 1/9240
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 30,40,77 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,40,77) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(30,40,77) x common factors =1 x 10 = 10
LCM(30,40,77) = ( 30 × 40 × 77 ) / 10
LCM(30,40,77) = 92400 / 10
LCM(30,40,77) = 9240
