Find LCM of 990,100,324,215,936 with Prime Factorization
| 2 | 990, 100, 324, 215, 936 |
| 2 | 495, 50, 162, 215, 468 |
| 3 | 495, 25, 81, 215, 234 |
| 3 | 165, 25, 27, 215, 78 |
| 5 | 55, 25, 9, 215, 26 |
| 11, 5, 9, 43, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 11 x 5 x 9 x 43 x 26 = 99613800
Therefore, the lowest common multiple of 990,100,324,215,936 is 99613800.
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.
990 x 100 x 324 x 215 x 936 = 6454974240000
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.
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
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
215 : 1, 5, 43, 215
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,100,324,215,936, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
100:2x 2x 5x 5
324:2x 2x 3x 3x 3x 3
215:5x 43
936:2x 2x 2x 3x 3x 13
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 2x 2x 3x 3x 3x 3x 5x 5 = 64800
Therefore, the value for common factors is 64800.
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 = 6454974240000/(1x64800)
LCM = 6454974240000/64800
LCM = 99613800
Thus, we can understand that the LCM of 990,100,324,215,936 is 99613800.
