Find LCM of 816,862,123,816 with Prime Factorization
| 2 | 816, 862, 123, 816 |
| 2 | 408, 431, 123, 408 |
| 2 | 204, 431, 123, 204 |
| 2 | 102, 431, 123, 102 |
| 3 | 51, 431, 123, 51 |
| 17 | 17, 431, 41, 17 |
| 1, 431, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 1 x 431 x 41 x 1 = 14419536
Therefore, the lowest common multiple of 816,862,123,816 is 14419536.
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 862 x 123 x 816 = 70598048256
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
862 : 1, 2, 431, 862
123 : 1, 3, 41, 123
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,862,123,816, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
862:2x 431
123:3x 41
816:2x 2x 2x 2x 3x 17
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 17 = 4896
Therefore, the value for common factors is 4896.
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 = 70598048256/(1x4896)
LCM = 70598048256/4896
LCM = 14419536
Thus, we can understand that the LCM of 816,862,123,816 is 14419536.
