Find LCM of 688,816,429,137,143 with Prime Factorization
| 2 | 688, 816, 429, 137, 143 |
| 2 | 344, 408, 429, 137, 143 |
| 2 | 172, 204, 429, 137, 143 |
| 2 | 86, 102, 429, 137, 143 |
| 3 | 43, 51, 429, 137, 143 |

| 13 | 43, 17, 13, 137, 13 |
| 43, 17, 1, 137, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 11 x 13 x 43 x 17 x 1 x 137 x 1 = 687409008
Therefore, the lowest common multiple of 688,816,429,137,143 is 687409008.
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.
688 x 816 x 429 x 137 x 143 = 4718375430912
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
429 : 1, 3, 11, 13, 33, 39, 143, 429
137 : 1, 137
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,816,429,137,143, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
816:2x 2x 2x 2x 3x 17
429:3x 11x 13
137:137
143:11x 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 3x 11x 13 = 6864
Therefore, the value for common factors is 6864.
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 = 4718375430912/(1x6864)
LCM = 4718375430912/6864
LCM = 687409008
Thus, we can understand that the LCM of 688,816,429,137,143 is 687409008.
