Find LCM of 858,485,582,689 with Prime Factorization
| 2 | 858, 485, 582, 689 |
| 3 | 429, 485, 291, 689 |
| 13 | 143, 485, 97, 689 |
| 97 | 11, 485, 97, 53 |
| 11, 5, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 97 x 11 x 5 x 1 x 53 = 22054890
Therefore, the lowest common multiple of 858,485,582,689 is 22054890.
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.
858 x 485 x 582 x 689 = 166867297740
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
485 : 1, 5, 97, 485
582 : 1, 2, 3, 6, 97, 194, 291, 582
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,485,582,689, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
485:5x 97
582:2x 3x 97
689:13x 53
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 13x 97 = 7566
Therefore, the value for common factors is 7566.
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 = 166867297740/(1x7566)
LCM = 166867297740/7566
LCM = 22054890
Thus, we can understand that the LCM of 858,485,582,689 is 22054890.
