Find LCM of 858,432,395,448,858 with Prime Factorization
| 2 | 858, 432, 395, 448, 858 |
| 2 | 429, 216, 395, 224, 429 |
| 2 | 429, 108, 395, 112, 429 |
| 2 | 429, 54, 395, 56, 429 |
| 3 | 429, 27, 395, 28, 429 |
| 11 | 143, 9, 395, 28, 143 |
| 13 | 13, 9, 395, 28, 13 |
| 1, 9, 395, 28, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 11 x 13 x 1 x 9 x 395 x 28 x 1 = 683242560
Therefore, the lowest common multiple of 858,432,395,448,858 is 683242560.
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.
858 x 432 x 395 x 448 x 858 = 56277323182080
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
395 : 1, 5, 79, 395
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,432,395,448,858, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
432:2x 2x 2x 2x 3x 3x 3
395:5x 79
448:2x 2x 2x 2x 2x 2x 7
858:2x 3x 11x 13
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 3x 11x 13 = 82368
Therefore, the value for common factors is 82368.
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 = 56277323182080/(1x82368)
LCM = 56277323182080/82368
LCM = 683242560
Thus, we can understand that the LCM of 858,432,395,448,858 is 683242560.
