Find LCM of 864,192,943,172 with Prime Factorization
| 2 | 864, 192, 943, 172 |
| 2 | 432, 96, 943, 86 |
| 2 | 216, 48, 943, 43 |
| 2 | 108, 24, 943, 43 |
| 2 | 54, 12, 943, 43 |
| 3 | 27, 6, 943, 43 |
| 9, 2, 943, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 9 x 2 x 943 x 43 = 70068672
Therefore, the lowest common multiple of 864,192,943,172 is 70068672.
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.
864 x 192 x 943 x 172 = 26906370048
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
943 : 1, 23, 41, 943
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,192,943,172, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
192:2x 2x 2x 2x 2x 2x 3
943:23x 41
172:2x 2x 43
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 2x 3 = 384
Therefore, the value for common factors is 384.
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 = 26906370048/(1x384)
LCM = 26906370048/384
LCM = 70068672
Thus, we can understand that the LCM of 864,192,943,172 is 70068672.
