1,11,29,319
Greatest Common Factor
We found the factors 328,180,319 . The biggest common factor number is the GCF number.
So the greatest common factor 328,180,319 is 1.
Lets's calculate LCM of 12,36,45
2 | 12, 36, 45 |
2 | 6, 18, 45 |
3 | 3, 9, 45 |
3 | 1, 3, 15 |
1, 1, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 1 x 1 x 5 = 180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/180
Therefore, the GCF of Fractions 328/12,180/36,319/45 is 1/180
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 12,36,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,36,45) = 3
common factors(in case of two or more numbers have common factors) = 36
GCF(12,36,45) x common factors =3 x 36 = 108
LCM(12,36,45) = ( 12 × 36 × 45 ) / 108
LCM(12,36,45) = 19440 / 108
LCM(12,36,45) = 180
