Given numbers are 797,513,687,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 797,513,687,391 is 36609005079.
Find LCM of 797,513,687,391 with Prime Factorization
| 3 | 797, 513, 687, 391 |
| 797, 171, 229, 391 |
Multiply the prime numbers at the bottom and the left side.
3 x 797 x 171 x 229 x 391 = 36609005079
Therefore, the lowest common multiple of 797,513,687,391 is 36609005079.
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.
797 x 513 x 687 x 391 = 109827015237
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.
797 : 1, 797
513 : 1, 3, 9, 19, 27, 57, 171, 513
687 : 1, 3, 229, 687
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,513,687,391, is 1.
Now, the common factors can be found like this.
797:797
513:3x 3x 3x 19
687:3x 229
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 109827015237/(1x3)
LCM = 109827015237/3
LCM = 36609005079
Thus, we can understand that the LCM of 797,513,687,391 is 36609005079.
