The LCM of 572,990,340,391 is 10064340.
Find LCM of 572,990,340,391 with Prime Factorization
| 2 | 572, 990, 340, 391 |
| 2 | 286, 495, 170, 391 |
| 5 | 143, 495, 85, 391 |
| 11 | 143, 99, 17, 391 |
| 17 | 13, 9, 17, 391 |
| 13, 9, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 17 x 13 x 9 x 1 x 23 = 10064340
Therefore, the lowest common multiple of 572,990,340,391 is 10064340.
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.
572 x 990 x 340 x 391 = 75281263200
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.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
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
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,990,340,391, is 1.
Now, the common factors can be found like this.
572:2x 2x 11x 13
990:2x 3x 3x 5x 11
340:2x 2x 5x 17
391:17x 23
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 2x 5x 11x 17 = 7480
Therefore, the value for common factors is 7480.
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 = 75281263200/(1x7480)
LCM = 75281263200/7480
LCM = 10064340
Thus, we can understand that the LCM of 572,990,340,391 is 10064340.
