Find LCM of 289,689,182,826,646 with Prime Factorization
| 2 | 289, 689, 182, 826, 646 |
| 7 | 289, 689, 91, 413, 323 |
| 13 | 289, 689, 13, 59, 323 |
| 17 | 289, 53, 1, 59, 323 |
| 17, 53, 1, 59, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 17 x 17 x 53 x 1 x 59 x 19 = 3125004974
Therefore, the lowest common multiple of 289,689,182,826,646 is 3125004974.
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.
289 x 689 x 182 x 826 x 646 = 19337530779112
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.
289 : 1, 17, 289
689 : 1, 13, 53, 689
182 : 1, 2, 7, 13, 14, 26, 91, 182
826 : 1, 2, 7, 14, 59, 118, 413, 826
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,689,182,826,646, is 1.
Now, the common factors can be found like this.
289:17x 17
689:13x 53
182:2x 7x 13
826:2x 7x 59
646:2x 17x 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 7x 13x 17 = 6188
Therefore, the value for common factors is 6188.
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 = 19337530779112/(1x6188)
LCM = 19337530779112/6188
LCM = 3125004974
Thus, we can understand that the LCM of 289,689,182,826,646 is 3125004974.
