Given numbers are 815,319,638,275
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,319,638,275 is 2599850.
Find LCM of 815,319,638,275 with Prime Factorization
| 5 | 815, 319, 638, 275 |
| 11 | 163, 319, 638, 55 |
| 29 | 163, 29, 58, 5 |
| 163, 1, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 29 x 163 x 1 x 2 x 5 = 2599850
Therefore, the lowest common multiple of 815,319,638,275 is 2599850.
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.
815 x 319 x 638 x 275 = 45614368250
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.
815 : 1, 5, 163, 815
319 : 1, 11, 29, 319
638 : 1, 2, 11, 22, 29, 58, 319, 638
275 : 1, 5, 11, 25, 55, 275
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,319,638,275, is 1.
Now, the common factors can be found like this.
815:5x 163
319:11x 29
638:2x 11x 29
275:5x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11x 29 = 17545
Therefore, the value for common factors is 17545.
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 = 45614368250/(1x17545)
LCM = 45614368250/17545
LCM = 2599850
Thus, we can understand that the LCM of 815,319,638,275 is 2599850.
