The LCM of 872,872,705,344 is 26434680.
Find LCM of 872,872,705,344 with Prime Factorization
| 2 | 872, 872, 705, 344 |
| 2 | 436, 436, 705, 172 |
| 2 | 218, 218, 705, 86 |
| 109 | 109, 109, 705, 43 |
| 1, 1, 705, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 109 x 1 x 1 x 705 x 43 = 26434680
Therefore, the lowest common multiple of 872,872,705,344 is 26434680.
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.
872 x 872 x 705 x 344 = 184408327680
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
872 : 1, 2, 4, 8, 109, 218, 436, 872
705 : 1, 3, 5, 15, 47, 141, 235, 705
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,872,705,344, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
872:2x 2x 2x 109
705:3x 5x 47
344:2x 2x 2x 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 2x 2x 109 = 6976
Therefore, the value for common factors is 6976.
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 = 184408327680/(1x6976)
LCM = 184408327680/6976
LCM = 26434680
Thus, we can understand that the LCM of 872,872,705,344 is 26434680.
