Given numbers are 808,697,856,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,697,856,838 is 25248869608.
Find LCM of 808,697,856,838 with Prime Factorization
| 2 | 808, 697, 856, 838 |
| 2 | 404, 697, 428, 419 |
| 2 | 202, 697, 214, 419 |
| 101, 697, 107, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 101 x 697 x 107 x 419 = 25248869608
Therefore, the lowest common multiple of 808,697,856,838 is 25248869608.
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.
808 x 697 x 856 x 838 = 403981913728
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
697 : 1, 17, 41, 697
856 : 1, 2, 4, 8, 107, 214, 428, 856
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,697,856,838, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
697:17x 41
856:2x 2x 2x 107
838:2x 419
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 2 = 16
Therefore, the value for common factors is 16.
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 = 403981913728/(1x16)
LCM = 403981913728/16
LCM = 25248869608
Thus, we can understand that the LCM of 808,697,856,838 is 25248869608.
