Greatest Common Factor
We found the factors 80,82,43,42 . The biggest common factor number is the GCF number.
So the greatest common factor 80,82,43,42 is 1.
Lets's calculate LCM of 32,45,30,561
2 | 32, 45, 30, 561 |
3 | 16, 45, 15, 561 |
5 | 16, 5, 15, 187 |
16, 1, 3, 187 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 16 x 1 x 3 x 187 = 269280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/269280
Therefore, the GCF of Fractions 80/32,82/45,43/30,42/561 is 1/269280
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 32,45,30,561 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(32,45,30,561) = 1
common factors(in case of two or more numbers have common factors) = 90
GCF(32,45,30,561) x common factors =1 x 90 = 90
LCM(32,45,30,561) = ( 32 × 45 × 30 × 561 ) / 90
LCM(32,45,30,561) = 24235200 / 90
LCM(32,45,30,561) = 269280
