Given numbers are 781,340,405,289,233
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,340,405,289,233 is 85196119140.
Find LCM of 781,340,405,289,233 with Prime Factorization
| 5 | 781, 340, 405, 289, 233 |
| 17 | 781, 68, 81, 289, 233 |
| 781, 4, 81, 17, 233 |
Multiply the prime numbers at the bottom and the left side.
5 x 17 x 781 x 4 x 81 x 17 x 233 = 85196119140
Therefore, the lowest common multiple of 781,340,405,289,233 is 85196119140.
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.
781 x 340 x 405 x 289 x 233 = 7241670126900
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.
781 : 1, 11, 71, 781
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
289 : 1, 17, 289
233 : 1, 233
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,340,405,289,233, is 1.
Now, the common factors can be found like this.
781:11x 71
340:2x 2x 5x 17
405:3x 3x 3x 3x 5
289:17x 17
233:233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 17 = 85
Therefore, the value for common factors is 85.
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 = 7241670126900/(1x85)
LCM = 7241670126900/85
LCM = 85196119140
Thus, we can understand that the LCM of 781,340,405,289,233 is 85196119140.
