Given numbers are 639,857,916,682,204
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,857,916,682,204 is 2907906606396.
Find LCM of 639,857,916,682,204 with Prime Factorization
| 2 | 639, 857, 916, 682, 204 |
| 2 | 639, 857, 458, 341, 102 |
| 3 | 639, 857, 229, 341, 51 |
| 213, 857, 229, 341, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 213 x 857 x 229 x 341 x 17 = 2907906606396
Therefore, the lowest common multiple of 639,857,916,682,204 is 2907906606396.
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.
639 x 857 x 916 x 682 x 204 = 69789758553504
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.
639 : 1, 3, 9, 71, 213, 639
857 : 1, 857
916 : 1, 2, 4, 229, 458, 916
682 : 1, 2, 11, 22, 31, 62, 341, 682
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,857,916,682,204, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
857:857
916:2x 2x 229
682:2x 11x 31
204:2x 2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 69789758553504/(1x24)
LCM = 69789758553504/24
LCM = 2907906606396
Thus, we can understand that the LCM of 639,857,916,682,204 is 2907906606396.
