Greatest Common Factor
We found the factors 47,63,19,71 . The biggest common factor number is the GCF number.
So the greatest common factor 47,63,19,71 is 1.
Lets's calculate LCM of 72,18,33,436
2 | 72, 18, 33, 436 |
2 | 36, 9, 33, 218 |
3 | 18, 9, 33, 109 |
3 | 6, 3, 11, 109 |
2, 1, 11, 109 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 2 x 1 x 11 x 109 = 86328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/86328
Therefore, the GCF of Fractions 47/72,63/18,19/33,71/436 is 1/86328
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 72,18,33,436 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,18,33,436) = 1
common factors(in case of two or more numbers have common factors) = 216
GCF(72,18,33,436) x common factors =1 x 216 = 216
LCM(72,18,33,436) = ( 72 × 18 × 33 × 436 ) / 216
LCM(72,18,33,436) = 18646848 / 216
LCM(72,18,33,436) = 86328
