Find LCM of 128,904,858,497,319 with Prime Factorization
| 2 | 128, 904, 858, 497, 319 |
| 2 | 64, 452, 429, 497, 319 |
| 2 | 32, 226, 429, 497, 319 |
| 11 | 16, 113, 429, 497, 319 |
| 16, 113, 39, 497, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 16 x 113 x 39 x 497 x 29 = 89433472128
Therefore, the lowest common multiple of 128,904,858,497,319 is 89433472128.
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.
128 x 904 x 858 x 497 x 319 = 15740291094528
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
904 : 1, 2, 4, 8, 113, 226, 452, 904
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
497 : 1, 7, 71, 497
319 : 1, 11, 29, 319
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,904,858,497,319, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
904:2x 2x 2x 113
858:2x 3x 11x 13
497:7x 71
319:11x 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 11 = 176
Therefore, the value for common factors is 176.
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 = 15740291094528/(1x176)
LCM = 15740291094528/176
LCM = 89433472128
Thus, we can understand that the LCM of 128,904,858,497,319 is 89433472128.
