The LCM of 873,408,556,357 is 115522344.
Find LCM of 873,408,556,357 with Prime Factorization
| 2 | 873, 408, 556, 357 |
| 2 | 873, 204, 278, 357 |
| 3 | 873, 102, 139, 357 |
| 17 | 291, 34, 139, 119 |
| 291, 2, 139, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 291 x 2 x 139 x 7 = 115522344
Therefore, the lowest common multiple of 873,408,556,357 is 115522344.
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.
873 x 408 x 556 x 357 = 70699674528
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.
873 : 1, 3, 9, 97, 291, 873
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
556 : 1, 2, 4, 139, 278, 556
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,408,556,357, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
408:2x 2x 2x 3x 17
556:2x 2x 139
357:3x 7x 17
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 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 70699674528/(1x612)
LCM = 70699674528/612
LCM = 115522344
Thus, we can understand that the LCM of 873,408,556,357 is 115522344.
