Given numbers are 159,636,578,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,636,578,920 is 42274920.
Find LCM of 159,636,578,920 with Prime Factorization
| 2 | 159, 636, 578, 920 |
| 2 | 159, 318, 289, 460 |
| 3 | 159, 159, 289, 230 |
| 53 | 53, 53, 289, 230 |
| 1, 1, 289, 230 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 1 x 1 x 289 x 230 = 42274920
Therefore, the lowest common multiple of 159,636,578,920 is 42274920.
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.
159 x 636 x 578 x 920 = 53773698240
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.
159 : 1, 3, 53, 159
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
578 : 1, 2, 17, 34, 289, 578
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,636,578,920, is 1.
Now, the common factors can be found like this.
159:3x 53
636:2x 2x 3x 53
578:2x 17x 17
920:2x 2x 2x 5x 23
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 3x 53 = 1272
Therefore, the value for common factors is 1272.
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 = 53773698240/(1x1272)
LCM = 53773698240/1272
LCM = 42274920
Thus, we can understand that the LCM of 159,636,578,920 is 42274920.
