Find LCM of 816,702,907,144 with Prime Factorization
| 2 | 816, 702, 907, 144 |
| 2 | 408, 351, 907, 72 |
| 2 | 204, 351, 907, 36 |
| 2 | 102, 351, 907, 18 |
| 3 | 51, 351, 907, 9 |
| 3 | 17, 117, 907, 3 |
| 17, 39, 907, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 17 x 39 x 907 x 1 = 86593104
Therefore, the lowest common multiple of 816,702,907,144 is 86593104.
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.
816 x 702 x 907 x 144 = 74816441856
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
907 : 1, 907
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,702,907,144, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
702:2x 3x 3x 3x 13
907:907
144:2x 2x 2x 2x 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 3 = 864
Therefore, the value for common factors is 864.
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 = 74816441856/(1x864)
LCM = 74816441856/864
LCM = 86593104
Thus, we can understand that the LCM of 816,702,907,144 is 86593104.
