Given numbers are 105,704,847,214,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,704,847,214,671 is 5307234240.
Find LCM of 105,704,847,214,671 with Prime Factorization
| 2 | 105, 704, 847, 214, 671 |
| 7 | 105, 352, 847, 107, 671 |
| 11 | 15, 352, 121, 107, 671 |
| 15, 32, 11, 107, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 15 x 32 x 11 x 107 x 61 = 5307234240
Therefore, the lowest common multiple of 105,704,847,214,671 is 5307234240.
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.
105 x 704 x 847 x 214 x 671 = 8990454802560
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
847 : 1, 7, 11, 77, 121, 847
214 : 1, 2, 107, 214
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,704,847,214,671, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
704:2x 2x 2x 2x 2x 2x 11
847:7x 11x 11
214:2x 107
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 11 = 1694
Therefore, the value for common factors is 1694.
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 = 8990454802560/(1x1694)
LCM = 8990454802560/1694
LCM = 5307234240
Thus, we can understand that the LCM of 105,704,847,214,671 is 5307234240.
