The LCM of 689,286,704,152 is 9216064.
Find LCM of 689,286,704,152 with Prime Factorization
| 2 | 689, 286, 704, 152 |
| 2 | 689, 143, 352, 76 |
| 2 | 689, 143, 176, 38 |
| 11 | 689, 143, 88, 19 |
| 13 | 689, 13, 8, 19 |
| 53, 1, 8, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 13 x 53 x 1 x 8 x 19 = 9216064
Therefore, the lowest common multiple of 689,286,704,152 is 9216064.
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.
689 x 286 x 704 x 152 = 21086354432
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.
689 : 1, 13, 53, 689
286 : 1, 2, 11, 13, 22, 26, 143, 286
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
152 : 1, 2, 4, 8, 19, 38, 76, 152
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,286,704,152, is 1.
Now, the common factors can be found like this.
689:13x 53
286:2x 11x 13
704:2x 2x 2x 2x 2x 2x 11
152:2x 2x 2x 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 11x 13 = 2288
Therefore, the value for common factors is 2288.
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 = 21086354432/(1x2288)
LCM = 21086354432/2288
LCM = 9216064
Thus, we can understand that the LCM of 689,286,704,152 is 9216064.
