Given numbers are 502,787,916,391,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 502,787,916,391,687 is 212247185316.
Find LCM of 502,787,916,391,687 with Prime Factorization
| 2 | 502, 787, 916, 391, 687 |
| 229 | 251, 787, 458, 391, 687 |
| 251, 787, 2, 391, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 229 x 251 x 787 x 2 x 391 x 3 = 212247185316
Therefore, the lowest common multiple of 502,787,916,391,687 is 212247185316.
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.
502 x 787 x 916 x 391 x 687 = 97209210874728
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.
502 : 1, 2, 251, 502
787 : 1, 787
916 : 1, 2, 4, 229, 458, 916
391 : 1, 17, 23, 391
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,787,916,391,687, is 1.
Now, the common factors can be found like this.
502:2x 251
787:787
916:2x 2x 229
391:17x 23
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 229 = 458
Therefore, the value for common factors is 458.
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 = 97209210874728/(1x458)
LCM = 97209210874728/458
LCM = 212247185316
Thus, we can understand that the LCM of 502,787,916,391,687 is 212247185316.
