Find LCM of 684,721,858,391,119 with Prime Factorization
| 2 | 684, 721, 858, 391, 119 |
| 3 | 342, 721, 429, 391, 119 |
| 7 | 114, 721, 143, 391, 119 |
| 17 | 114, 103, 143, 391, 17 |
| 114, 103, 143, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 114 x 103 x 143 x 23 x 1 = 27574278732
Therefore, the lowest common multiple of 684,721,858,391,119 is 27574278732.
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.
684 x 721 x 858 x 391 x 119 = 19688035014648
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
721 : 1, 7, 103, 721
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
391 : 1, 17, 23, 391
119 : 1, 7, 17, 119
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,721,858,391,119, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
721:7x 103
858:2x 3x 11x 13
391:17x 23
119:7x 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 3x 7x 17 = 714
Therefore, the value for common factors is 714.
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 = 19688035014648/(1x714)
LCM = 19688035014648/714
LCM = 27574278732
Thus, we can understand that the LCM of 684,721,858,391,119 is 27574278732.
