Given numbers are 638,923,850,605,498
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,923,850,605,498 is 685493501550.
Find LCM of 638,923,850,605,498 with Prime Factorization
| 2 | 638, 923, 850, 605, 498 |
| 5 | 319, 923, 425, 605, 249 |
| 11 | 319, 923, 85, 121, 249 |
| 29, 923, 85, 11, 249 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 29 x 923 x 85 x 11 x 249 = 685493501550
Therefore, the lowest common multiple of 638,923,850,605,498 is 685493501550.
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.
638 x 923 x 850 x 605 x 498 = 150808570341000
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
923 : 1, 13, 71, 923
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
605 : 1, 5, 11, 55, 121, 605
498 : 1, 2, 3, 6, 83, 166, 249, 498
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,923,850,605,498, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
923:13x 71
850:2x 5x 5x 17
605:5x 11x 11
498:2x 3x 83
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 150808570341000/(1x220)
LCM = 150808570341000/220
LCM = 685493501550
Thus, we can understand that the LCM of 638,923,850,605,498 is 685493501550.
