Given numbers are 473,990,162,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,990,162,393 is 50190030.
Find LCM of 473,990,162,393 with Prime Factorization
| 2 | 473, 990, 162, 393 |
| 3 | 473, 495, 81, 393 |
| 3 | 473, 165, 27, 131 |
| 11 | 473, 55, 9, 131 |
| 43, 5, 9, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 43 x 5 x 9 x 131 = 50190030
Therefore, the lowest common multiple of 473,990,162,393 is 50190030.
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.
473 x 990 x 162 x 393 = 29812877820
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.
473 : 1, 11, 43, 473
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
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,990,162,393, is 1.
Now, the common factors can be found like this.
473:11x 43
990:2x 3x 3x 5x 11
162:2x 3x 3x 3x 3
393:3x 131
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 11 = 594
Therefore, the value for common factors is 594.
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 = 29812877820/(1x594)
LCM = 29812877820/594
LCM = 50190030
Thus, we can understand that the LCM of 473,990,162,393 is 50190030.
