The LCM of 549,399,209,945 is 12047805.
Find LCM of 549,399,209,945 with Prime Factorization
| 3 | 549, 399, 209, 945 |
| 3 | 183, 133, 209, 315 |
| 7 | 61, 133, 209, 105 |
| 19 | 61, 19, 209, 15 |
| 61, 1, 11, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 19 x 61 x 1 x 11 x 15 = 12047805
Therefore, the lowest common multiple of 549,399,209,945 is 12047805.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
549 x 399 x 209 x 945 = 43263667755
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
549 : 1, 3, 9, 61, 183, 549
399 : 1, 3, 7, 19, 21, 57, 133, 399
209 : 1, 11, 19, 209
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,399,209,945, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
399:3x 7x 19
209:11x 19
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 19 = 3591
Therefore, the value for common factors is 3591.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 43263667755/(1x3591)
LCM = 43263667755/3591
LCM = 12047805
Thus, we can understand that the LCM of 549,399,209,945 is 12047805.
