| 3 | 823, 11, 915, 5, 165 |
| 5 | 823, 11, 305, 5, 55 |
| 11 | 823, 11, 61, 1, 11 |
| 823, 1, 61, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 11 x 823 x 1 x 61 x 1 x 1 = 530143680
Therefore, the lowest common multiple of 823,704,915,320,165 is 530143680.
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.
823 x 704 x 915 x 320 x 165 = 27991586304000
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.
823 : 1, 823
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
915 : 1, 3, 5, 15, 61, 183, 305, 915
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,704,915,320,165, is 1.
Now, the common factors can be found like this.
823:823
704:2x 2x 2x 2x 2x 2x 11
915:3x 5x 61
320:2x 2x 2x 2x 2x 2x 5
165:3x 5x 11
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 2x 2x 2x 3x 5x 5x 11 = 52800
Therefore, the value for common factors is 52800.
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 = 27991586304000/(1x52800)
LCM = 27991586304000/52800
LCM = 530143680
Thus, we can understand that the LCM of 823,704,915,320,165 is 530143680.
