Given numbers are 268,407,164,634,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 268,407,164,634,287 is 9923625404.
Find LCM of 268,407,164,634,287 with Prime Factorization
| 2 | 268, 407, 164, 634, 287 |
| 2 | 134, 407, 82, 317, 287 |
| 41 | 67, 407, 41, 317, 287 |
| 67, 407, 1, 317, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 67 x 407 x 1 x 317 x 7 = 9923625404
Therefore, the lowest common multiple of 268,407,164,634,287 is 9923625404.
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.
268 x 407 x 164 x 634 x 287 = 3254949132512
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.
268 : 1, 2, 4, 67, 134, 268
407 : 1, 11, 37, 407
164 : 1, 2, 4, 41, 82, 164
634 : 1, 2, 317, 634
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 268,407,164,634,287, is 1.
Now, the common factors can be found like this.
268:2x 2x 67
407:11x 37
164:2x 2x 41
634:2x 317
287:7x 41
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 41 = 328
Therefore, the value for common factors is 328.
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 = 3254949132512/(1x328)
LCM = 3254949132512/328
LCM = 9923625404
Thus, we can understand that the LCM of 268,407,164,634,287 is 9923625404.
