Given numbers are 405,979,319,279,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,979,319,279,636 is 75567189060.
Find LCM of 405,979,319,279,636 with Prime Factorization
| 3 | 405, 979, 319, 279, 636 |
| 3 | 135, 979, 319, 93, 212 |
| 11 | 45, 979, 319, 31, 212 |
| 45, 89, 29, 31, 212 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 45 x 89 x 29 x 31 x 212 = 75567189060
Therefore, the lowest common multiple of 405,979,319,279,636 is 75567189060.
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.
405 x 979 x 319 x 279 x 636 = 22443455150820
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
979 : 1, 11, 89, 979
319 : 1, 11, 29, 319
279 : 1, 3, 9, 31, 93, 279
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,979,319,279,636, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
979:11x 89
319:11x 29
279:3x 3x 31
636:2x 2x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 11 = 297
Therefore, the value for common factors is 297.
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 = 22443455150820/(1x297)
LCM = 22443455150820/297
LCM = 75567189060
Thus, we can understand that the LCM of 405,979,319,279,636 is 75567189060.
