Lets's calculate LCM of 21,77,47
7 | 21, 77, 47 |
3, 11, 47 |
∴ So the LCM of the given numbers is 7 x 3 x 11 x 47 = 10857
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/10857
Therefore, the GCF of Fractions 2/21,816/77,344/47 is 2/10857
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 21,77,47 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,77,47) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(21,77,47) x common factors =1 x 7 = 7
LCM(21,77,47) = ( 21 × 77 × 47 ) / 7
LCM(21,77,47) = 75999 / 7
LCM(21,77,47) = 10857
