Given numbers are 731,338,396,788,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,338,396,788,793 is 587888992548.
Find LCM of 731,338,396,788,793 with Prime Factorization
| 2 | 731, 338, 396, 788, 793 |
| 2 | 731, 169, 198, 394, 793 |
| 13 | 731, 169, 99, 197, 793 |
| 731, 13, 99, 197, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 731 x 13 x 99 x 197 x 61 = 587888992548
Therefore, the lowest common multiple of 731,338,396,788,793 is 587888992548.
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.
731 x 338 x 396 x 788 x 793 = 61140455224992
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.
731 : 1, 17, 43, 731
338 : 1, 2, 13, 26, 169, 338
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
788 : 1, 2, 4, 197, 394, 788
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,338,396,788,793, is 1.
Now, the common factors can be found like this.
731:17x 43
338:2x 13x 13
396:2x 2x 3x 3x 11
788:2x 2x 197
793:13x 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 2x 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 61140455224992/(1x104)
LCM = 61140455224992/104
LCM = 587888992548
Thus, we can understand that the LCM of 731,338,396,788,793 is 587888992548.
