Given numbers are 261,923,735,355,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,923,735,355,438 is 8617100310.
Find LCM of 261,923,735,355,438 with Prime Factorization
| 3 | 261, 923, 735, 355, 438 |
| 5 | 87, 923, 245, 355, 146 |
| 71 | 87, 923, 49, 71, 146 |
| 87, 13, 49, 1, 146 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 71 x 87 x 13 x 49 x 1 x 146 = 8617100310
Therefore, the lowest common multiple of 261,923,735,355,438 is 8617100310.
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.
261 x 923 x 735 x 355 x 438 = 27531635490450
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.
261 : 1, 3, 9, 29, 87, 261
923 : 1, 13, 71, 923
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
355 : 1, 5, 71, 355
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,923,735,355,438, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
923:13x 71
735:3x 5x 7x 7
355:5x 71
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 71 = 3195
Therefore, the value for common factors is 3195.
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 = 27531635490450/(1x3195)
LCM = 27531635490450/3195
LCM = 8617100310
Thus, we can understand that the LCM of 261,923,735,355,438 is 8617100310.
