Given numbers are 231,459,336,915,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,459,336,915,923 is 159193354320.
Find LCM of 231,459,336,915,923 with Prime Factorization
| 3 | 231, 459, 336, 915, 923 |
| 7 | 77, 153, 112, 305, 923 |
| 11, 153, 16, 305, 923 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 153 x 16 x 305 x 923 = 159193354320
Therefore, the lowest common multiple of 231,459,336,915,923 is 159193354320.
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.
231 x 459 x 336 x 915 x 923 = 30087543966480
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
459 : 1, 3, 9, 17, 27, 51, 153, 459
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
915 : 1, 3, 5, 15, 61, 183, 305, 915
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,459,336,915,923, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
459:3x 3x 3x 17
336:2x 2x 2x 2x 3x 7
915:3x 5x 61
923:13x 71
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 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 30087543966480/(1x189)
LCM = 30087543966480/189
LCM = 159193354320
Thus, we can understand that the LCM of 231,459,336,915,923 is 159193354320.
