Find LCM of 208,858,491,424,387 with Prime Factorization
| 2 | 208, 858, 491, 424, 387 |
| 2 | 104, 429, 491, 212, 387 |
| 2 | 52, 429, 491, 106, 387 |
| 3 | 26, 429, 491, 53, 387 |
| 13 | 26, 143, 491, 53, 129 |
| 2, 11, 491, 53, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 2 x 11 x 491 x 53 x 129 = 23042221488
Therefore, the lowest common multiple of 208,858,491,424,387 is 23042221488.
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.
208 x 858 x 491 x 424 x 387 = 14378346208512
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
491 : 1, 491
424 : 1, 2, 4, 8, 53, 106, 212, 424
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,858,491,424,387, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
858:2x 3x 11x 13
491:491
424:2x 2x 2x 53
387:3x 3x 43
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 3x 13 = 624
Therefore, the value for common factors is 624.
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 = 14378346208512/(1x624)
LCM = 14378346208512/624
LCM = 23042221488
Thus, we can understand that the LCM of 208,858,491,424,387 is 23042221488.
