So the greatest common factor 780,771,600 is 3.
Lets's calculate LCM of 70,72,47
2 | 70, 72, 47 |
35, 36, 47 |
∴ So the LCM of the given numbers is 2 x 35 x 36 x 47 = 118440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/118440
Therefore, the GCF of Fractions 780/70,771/72,600/47 is 3/118440
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 70,72,47 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,72,47) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(70,72,47) x common factors =1 x 2 = 2
LCM(70,72,47) = ( 70 × 72 × 47 ) / 2
LCM(70,72,47) = 236880 / 2
LCM(70,72,47) = 118440
