So the greatest common factor 839,792,523 is 1.
Lets's calculate LCM of 47,30,40
2 | 47, 30, 40 |
5 | 47, 15, 20 |
47, 3, 4 |
∴ So the LCM of the given numbers is 2 x 5 x 47 x 3 x 4 = 5640
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5640
Therefore, the GCF of Fractions 839/47,792/30,523/40 is 1/5640
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 47,30,40 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,30,40) = 1
common factors(in case of two or more numbers have common factors) = 10
GCF(47,30,40) x common factors =1 x 10 = 10
LCM(47,30,40) = ( 47 × 30 × 40 ) / 10
LCM(47,30,40) = 56400 / 10
LCM(47,30,40) = 5640
