Given numbers are 832,405,817,731,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 832,405,817,731,705 is 219961759680.
Find LCM of 832,405,817,731,705 with Prime Factorization
| 3 | 832, 405, 817, 731, 705 |
| 5 | 832, 135, 817, 731, 235 |
| 43 | 832, 27, 817, 731, 47 |
| 832, 27, 19, 17, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 832 x 27 x 19 x 17 x 47 = 219961759680
Therefore, the lowest common multiple of 832,405,817,731,705 is 219961759680.
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.
832 x 405 x 817 x 731 x 705 = 141875334993600
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.
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
817 : 1, 19, 43, 817
731 : 1, 17, 43, 731
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 832,405,817,731,705, is 1.
Now, the common factors can be found like this.
832:2x 2x 2x 2x 2x 2x 13
405:3x 3x 3x 3x 5
817:19x 43
731:17x 43
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 43 = 645
Therefore, the value for common factors is 645.
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 = 141875334993600/(1x645)
LCM = 141875334993600/645
LCM = 219961759680
Thus, we can understand that the LCM of 832,405,817,731,705 is 219961759680.
