Given numbers are 995,665,208,247,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 995,665,208,247,638 is 8780691920.
Find LCM of 995,665,208,247,638 with Prime Factorization
| 2 | 995, 665, 208, 247, 638 |
| 5 | 995, 665, 104, 247, 319 |
| 13 | 199, 133, 104, 247, 319 |
| 19 | 199, 133, 8, 19, 319 |
| 199, 7, 8, 1, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 19 x 199 x 7 x 8 x 1 x 319 = 8780691920
Therefore, the lowest common multiple of 995,665,208,247,638 is 8780691920.
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.
995 x 665 x 208 x 247 x 638 = 21688309042400
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.
995 : 1, 5, 199, 995
665 : 1, 5, 7, 19, 35, 95, 133, 665
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
247 : 1, 13, 19, 247
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 995,665,208,247,638, is 1.
Now, the common factors can be found like this.
995:5x 199
665:5x 7x 19
208:2x 2x 2x 2x 13
247:13x 19
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13x 19 = 2470
Therefore, the value for common factors is 2470.
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 = 21688309042400/(1x2470)
LCM = 21688309042400/2470
LCM = 8780691920
Thus, we can understand that the LCM of 995,665,208,247,638 is 8780691920.
