Given numbers are 636,115,391,709
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,115,391,709 is 881556420.
Find LCM of 636,115,391,709 with Prime Factorization
| 23 | 636, 115, 391, 709 |
| 636, 5, 17, 709 |
Multiply the prime numbers at the bottom and the left side.
23 x 636 x 5 x 17 x 709 = 881556420
Therefore, the lowest common multiple of 636,115,391,709 is 881556420.
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.
636 x 115 x 391 x 709 = 20275797660
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
115 : 1, 5, 23, 115
391 : 1, 17, 23, 391
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,115,391,709, is 1.
Now, the common factors can be found like this.
636:2x 2x 3x 53
115:5x 23
391:17x 23
709:709
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 20275797660/(1x23)
LCM = 20275797660/23
LCM = 881556420
Thus, we can understand that the LCM of 636,115,391,709 is 881556420.
