So the greatest common factor 81,719,536 is 1.
Lets's calculate LCM of 53,21,459
3 | 53, 21, 459 |
53, 7, 153 |
∴ So the LCM of the given numbers is 3 x 53 x 7 x 153 = 170289
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/170289
Therefore, the GCF of Fractions 81/53,719/21,536/459 is 1/170289
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 53,21,459 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(53,21,459) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(53,21,459) x common factors =1 x 3 = 3
LCM(53,21,459) = ( 53 × 21 × 459 ) / 3
LCM(53,21,459) = 510867 / 3
LCM(53,21,459) = 170289
