Given numbers are 503,987,391,329
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 503,987,391,329 is 194116251.
Find LCM of 503,987,391,329 with Prime Factorization
| 7 | 503, 987, 391, 329 |
| 47 | 503, 141, 391, 47 |
| 503, 3, 391, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 47 x 503 x 3 x 391 x 1 = 194116251
Therefore, the lowest common multiple of 503,987,391,329 is 194116251.
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.
503 x 987 x 391 x 329 = 63864246579
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.
503 : 1, 503
987 : 1, 3, 7, 21, 47, 141, 329, 987
391 : 1, 17, 23, 391
329 : 1, 7, 47, 329
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 503,987,391,329, is 1.
Now, the common factors can be found like this.
503:503
987:3x 7x 47
391:17x 23
329:7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 47 = 329
Therefore, the value for common factors is 329.
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 = 63864246579/(1x329)
LCM = 63864246579/329
LCM = 194116251
Thus, we can understand that the LCM of 503,987,391,329 is 194116251.
