Greatest Common Factor
We found the factors 69,67,32,43 . The biggest common factor number is the GCF number.
So the greatest common factor 69,67,32,43 is 1.
Lets's calculate LCM of 33,96,90,16
2 | 33, 96, 90, 16 |
2 | 33, 48, 45, 8 |
2 | 33, 24, 45, 4 |
2 | 33, 12, 45, 2 |
3 | 33, 6, 45, 1 |
11, 2, 15, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 11 x 2 x 15 x 1 = 15840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15840
Therefore, the GCF of Fractions 69/33,67/96,32/90,43/16 is 1/15840
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 33,96,90,16 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(33,96,90,16) = 1
common factors(in case of two or more numbers have common factors) = 288
GCF(33,96,90,16) x common factors =1 x 288 = 288
LCM(33,96,90,16) = ( 33 × 96 × 90 × 16 ) / 288
LCM(33,96,90,16) = 4561920 / 288
LCM(33,96,90,16) = 15840
