Greatest Common Factor
We found the factors 57,28,96,922 . The biggest common factor number is the GCF number.
So the greatest common factor 57,28,96,922 is 1.
Lets's calculate LCM of 15,60,87,30
2 | 15, 60, 87, 30 |
3 | 15, 30, 87, 15 |
5 | 5, 10, 29, 5 |
1, 2, 29, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 2 x 29 x 1 = 1740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1740
Therefore, the GCF of Fractions 57/15,28/60,96/87,922/30 is 1/1740
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 15,60,87,30 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,60,87,30) = 3
common factors(in case of two or more numbers have common factors) = 450
GCF(15,60,87,30) x common factors =3 x 450 = 1350
LCM(15,60,87,30) = ( 15 × 60 × 87 × 30 ) / 1350
LCM(15,60,87,30) = 2349000 / 1350
LCM(15,60,87,30) = 1740
