Given numbers are 100,500,920,636,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 100,500,920,636,478 is 874023000.
Find LCM of 100,500,920,636,478 with Prime Factorization
| 2 | 100, 500, 920, 636, 478 |
| 2 | 50, 250, 460, 318, 239 |
| 5 | 25, 125, 230, 159, 239 |
| 5 | 5, 25, 46, 159, 239 |
| 1, 5, 46, 159, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 1 x 5 x 46 x 159 x 239 = 874023000
Therefore, the lowest common multiple of 100,500,920,636,478 is 874023000.
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.
100 x 500 x 920 x 636 x 478 = 13984368000000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
478 : 1, 2, 239, 478
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,500,920,636,478, is 2.
Now, the common factors can be found like this.
100:2x 2x 5x 5
500:2x 2x 5x 5x 5
920:2x 2x 2x 5x 23
636:2x 2x 3x 53
478:2x 239
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 2x 5x 5x 5 = 8000
Therefore, the value for common factors is 8000.
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 = 13984368000000/(2x8000)
LCM = 13984368000000/16000
LCM = 874023000
Thus, we can understand that the LCM of 100,500,920,636,478 is 874023000.
