Find LCM of 286,238,391,384,928 with Prime Factorization
| 2 | 286, 238, 391, 384, 928 |
| 2 | 143, 119, 391, 192, 464 |
| 2 | 143, 119, 391, 96, 232 |
| 2 | 143, 119, 391, 48, 116 |
| 2 | 143, 119, 391, 24, 58 |
| 17 | 143, 119, 391, 12, 29 |
| 143, 7, 23, 12, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 17 x 143 x 7 x 23 x 12 x 29 = 4358530176
Therefore, the lowest common multiple of 286,238,391,384,928 is 4358530176.
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.
286 x 238 x 391 x 384 x 928 = 9484161662976
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
238 : 1, 2, 7, 14, 17, 34, 119, 238
391 : 1, 17, 23, 391
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,238,391,384,928, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
238:2x 7x 17
391:17x 23
384:2x 2x 2x 2x 2x 2x 2x 3
928:2x 2x 2x 2x 2x 29
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 17 = 2176
Therefore, the value for common factors is 2176.
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 = 9484161662976/(1x2176)
LCM = 9484161662976/2176
LCM = 4358530176
Thus, we can understand that the LCM of 286,238,391,384,928 is 4358530176.
