Find LCM of 158,432,990,514,815 with Prime Factorization
| 2 | 158, 432, 990, 514, 815 |
| 3 | 79, 216, 495, 257, 815 |
| 3 | 79, 72, 165, 257, 815 |
| 5 | 79, 24, 55, 257, 815 |
| 79, 24, 11, 257, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 79 x 24 x 11 x 257 x 163 = 78631082640
Therefore, the lowest common multiple of 158,432,990,514,815 is 78631082640.
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.
158 x 432 x 990 x 514 x 815 = 28307189750400
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.
158 : 1, 2, 79, 158
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
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
514 : 1, 2, 257, 514
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,432,990,514,815, is 1.
Now, the common factors can be found like this.
158:2x 79
432:2x 2x 2x 2x 3x 3x 3
990:2x 3x 3x 5x 11
514:2x 257
815:5x 163
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 28307189750400/(1x360)
LCM = 28307189750400/360
LCM = 78631082640
Thus, we can understand that the LCM of 158,432,990,514,815 is 78631082640.
