Given numbers are 549,396,394,330,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,396,394,330,981 is 2593508940.
Find LCM of 549,396,394,330,981 with Prime Factorization
| 2 | 549, 396, 394, 330, 981 |
| 3 | 549, 198, 197, 165, 981 |
| 3 | 183, 66, 197, 55, 327 |
| 11 | 61, 22, 197, 55, 109 |
| 61, 2, 197, 5, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 61 x 2 x 197 x 5 x 109 = 2593508940
Therefore, the lowest common multiple of 549,396,394,330,981 is 2593508940.
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 396 x 394 x 330 x 981 = 27729797586480
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
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
394 : 1, 2, 197, 394
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,396,394,330,981, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
396:2x 2x 3x 3x 11
394:2x 197
330:2x 3x 5x 11
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3x 3x 11 = 10692
Therefore, the value for common factors is 10692.
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 = 27729797586480/(1x10692)
LCM = 27729797586480/10692
LCM = 2593508940
Thus, we can understand that the LCM of 549,396,394,330,981 is 2593508940.
