Find LCM of 361,290,108,741,864 with Prime Factorization
| 2 | 361, 290, 108, 741, 864 |
| 2 | 361, 145, 54, 741, 432 |
| 3 | 361, 145, 27, 741, 216 |
| 3 | 361, 145, 9, 247, 72 |
| 3 | 361, 145, 3, 247, 24 |
| 19 | 361, 145, 1, 247, 8 |
| 19, 145, 1, 13, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 19 x 19 x 145 x 1 x 13 x 8 = 587939040
Therefore, the lowest common multiple of 361,290,108,741,864 is 587939040.
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.
361 x 290 x 108 x 741 x 864 = 7238705460480
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.
361 : 1, 19, 361
290 : 1, 2, 5, 10, 29, 58, 145, 290
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
741 : 1, 3, 13, 19, 39, 57, 247, 741
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,290,108,741,864, is 1.
Now, the common factors can be found like this.
361:19x 19
290:2x 5x 29
108:2x 2x 3x 3x 3
741:3x 13x 19
864:2x 2x 2x 2x 2x 3x 3x 3
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 3x 3x 3x 3x 19 = 12312
Therefore, the value for common factors is 12312.
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 = 7238705460480/(1x12312)
LCM = 7238705460480/12312
LCM = 587939040
Thus, we can understand that the LCM of 361,290,108,741,864 is 587939040.
