Find LCM of 558,497,476,990 with Prime Factorization
| 2 | 558, 497, 476, 990 |
| 3 | 279, 497, 238, 495 |
| 3 | 93, 497, 238, 165 |
| 7 | 31, 497, 238, 55 |
| 31, 71, 34, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 31 x 71 x 34 x 55 = 518599620
Therefore, the lowest common multiple of 558,497,476,990 is 518599620.
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.
558 x 497 x 476 x 990 = 130687104240
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
497 : 1, 7, 71, 497
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,497,476,990, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
497:7x 71
476:2x 2x 7x 17
990:2x 3x 3x 5x 11
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 7 = 252
Therefore, the value for common factors is 252.
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 = 130687104240/(1x252)
LCM = 130687104240/252
LCM = 518599620
Thus, we can understand that the LCM of 558,497,476,990 is 518599620.
