:1,2,11,22,23,46,253,506
Greatest Common Factor
We found the factors 80,281,506 . The biggest common factor number is the GCF number.
So the greatest common factor 80,281,506 is 1.
Lets's calculate LCM of 47,39,897
3 | 47, 39, 897 |
13 | 47, 13, 299 |
47, 1, 23 |
∴ So the LCM of the given numbers is 3 x 13 x 47 x 1 x 23 = 42159
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/42159
Therefore, the GCF of Fractions 80/47,281/39,506/897 is 1/42159
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 47,39,897 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,39,897) = 1
common factors(in case of two or more numbers have common factors) = 39
GCF(47,39,897) x common factors =1 x 39 = 39
LCM(47,39,897) = ( 47 × 39 × 897 ) / 39
LCM(47,39,897) = 1644201 / 39
LCM(47,39,897) = 42159
