Find LCM of 117,391,990,435,544 with Prime Factorization
| 2 | 117, 391, 990, 435, 544 |
| 3 | 117, 391, 495, 435, 272 |
| 3 | 39, 391, 165, 145, 272 |
| 5 | 13, 391, 55, 145, 272 |
| 17 | 13, 391, 11, 29, 272 |
| 13, 23, 11, 29, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 13 x 23 x 11 x 29 x 16 = 2334926880
Therefore, the lowest common multiple of 117,391,990,435,544 is 2334926880.
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.
117 x 391 x 990 x 435 x 544 = 10717314379200
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.
117 : 1, 3, 9, 13, 39, 117
391 : 1, 17, 23, 391
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
435 : 1, 3, 5, 15, 29, 87, 145, 435
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,391,990,435,544, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
391:17x 23
990:2x 3x 3x 5x 11
435:3x 5x 29
544:2x 2x 2x 2x 2x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 17 = 4590
Therefore, the value for common factors is 4590.
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 = 10717314379200/(1x4590)
LCM = 10717314379200/4590
LCM = 2334926880
Thus, we can understand that the LCM of 117,391,990,435,544 is 2334926880.
