Greatest Common Factor
We found the factors 53,48,90,93 . The biggest common factor number is the GCF number.
So the greatest common factor 53,48,90,93 is 1.
Lets's calculate LCM of 36,45,90,15
2 | 36, 45, 90, 15 |
3 | 18, 45, 45, 15 |
3 | 6, 5, 15, 15 |
5 | 2, 5, 5, 5 |
2, 1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 2 x 1 x 1 x 1 = 180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/180
Therefore, the GCF of Fractions 53/36,48/45,90/90,93/15 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 36,45,90,15 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(36,45,90,15) = 3
common factors(in case of two or more numbers have common factors) = 4050
GCF(36,45,90,15) x common factors =3 x 4050 = 12150
LCM(36,45,90,15) = ( 36 × 45 × 90 × 15 ) / 12150
LCM(36,45,90,15) = 2187000 / 12150
LCM(36,45,90,15) = 180
