Greatest Common Factor
We found the factors 20,72,483 . The biggest common factor number is the GCF number.
So the greatest common factor 20,72,483 is 1.
Lets's calculate LCM of 16,45,471
3 | 16, 45, 471 |
16, 15, 157 |
∴ So the LCM of the given numbers is 3 x 16 x 15 x 157 = 113040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/113040
Therefore, the GCF of Fractions 20/16,72/45,483/471 is 1/113040
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 16,45,471 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,45,471) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(16,45,471) x common factors =1 x 3 = 3
LCM(16,45,471) = ( 16 × 45 × 471 ) / 3
LCM(16,45,471) = 339120 / 3
LCM(16,45,471) = 113040
