The LCM of 400,162,307,822,216 is 1362711600.
Find LCM of 400,162,307,822,216 with Prime Factorization
| 2 | 400, 162, 307, 822, 216 |
| 2 | 200, 81, 307, 411, 108 |
| 2 | 100, 81, 307, 411, 54 |
| 3 | 50, 81, 307, 411, 27 |
| 3 | 50, 9, 307, 137, 27 |
| 3 | 50, 3, 307, 137, 9 |
| 50, 1, 307, 137, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 50 x 1 x 307 x 137 x 3 = 1362711600
Therefore, the lowest common multiple of 400,162,307,822,216 is 1362711600.
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.
400 x 162 x 307 x 822 x 216 = 3532148467200
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.
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
307 : 1, 307
822 : 1, 2, 3, 6, 137, 274, 411, 822
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,162,307,822,216, is 1.
Now, the common factors can be found like this.
400:2x 2x 2x 2x 5x 5
162:2x 3x 3x 3x 3
307:307
822:2x 3x 137
216:2x 2x 2x 3x 3x 3
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 3 = 2592
Therefore, the value for common factors is 2592.
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 = 3532148467200/(1x2592)
LCM = 3532148467200/2592
LCM = 1362711600
Thus, we can understand that the LCM of 400,162,307,822,216 is 1362711600.
