Given numbers are 682,136,304,684
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,136,304,684 is 15860592.
Find LCM of 682,136,304,684 with Prime Factorization
| 2 | 682, 136, 304, 684 |
| 2 | 341, 68, 152, 342 |
| 2 | 341, 34, 76, 171 |
| 19 | 341, 17, 38, 171 |
| 341, 17, 2, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 341 x 17 x 2 x 9 = 15860592
Therefore, the lowest common multiple of 682,136,304,684 is 15860592.
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.
682 x 136 x 304 x 684 = 19286479872
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
136 : 1, 2, 4, 8, 17, 34, 68, 136
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,136,304,684, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
136:2x 2x 2x 17
304:2x 2x 2x 2x 19
684:2x 2x 3x 3x 19
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 19 = 608
Therefore, the value for common factors is 608.
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 = 19286479872/(2x608)
LCM = 19286479872/1216
LCM = 15860592
Thus, we can understand that the LCM of 682,136,304,684 is 15860592.
