Given numbers are 826,638,319,206,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 826,638,319,206,731 is 19839253742.
Find LCM of 826,638,319,206,731 with Prime Factorization
| 2 | 826, 638, 319, 206, 731 |
| 11 | 413, 319, 319, 103, 731 |
| 29 | 413, 29, 29, 103, 731 |
| 413, 1, 1, 103, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 413 x 1 x 1 x 103 x 731 = 19839253742
Therefore, the lowest common multiple of 826,638,319,206,731 is 19839253742.
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.
826 x 638 x 319 x 206 x 731 = 25314887774792
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
638 : 1, 2, 11, 22, 29, 58, 319, 638
319 : 1, 11, 29, 319
206 : 1, 2, 103, 206
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,638,319,206,731, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
638:2x 11x 29
319:11x 29
206:2x 103
731:17x 43
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 11x 29 = 1276
Therefore, the value for common factors is 1276.
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 = 25314887774792/(1x1276)
LCM = 25314887774792/1276
LCM = 19839253742
Thus, we can understand that the LCM of 826,638,319,206,731 is 19839253742.
