Find LCM of 384,219,834,360,642 with Prime Factorization
| 2 | 384, 219, 834, 360, 642 |
| 2 | 192, 219, 417, 180, 321 |
| 2 | 96, 219, 417, 90, 321 |
| 3 | 48, 219, 417, 45, 321 |
| 16, 73, 139, 15, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 16 x 73 x 139 x 15 x 107 = 6253799040
Therefore, the lowest common multiple of 384,219,834,360,642 is 6253799040.
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.
384 x 219 x 834 x 360 x 642 = 16209847111680
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.
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
219 : 1, 3, 73, 219
834 : 1, 2, 3, 6, 139, 278, 417, 834
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
642 : 1, 2, 3, 6, 107, 214, 321, 642
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 384,219,834,360,642, is 3.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
219:3x 73
834:2x 3x 139
360:2x 2x 2x 3x 3x 5
642:2x 3x 107
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 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 16209847111680/(3x864)
LCM = 16209847111680/2592
LCM = 6253799040
Thus, we can understand that the LCM of 384,219,834,360,642 is 6253799040.
