Given numbers are 208,507,808,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 208,507,808,816 is 13928304.
Find LCM of 208,507,808,816 with Prime Factorization
| 2 | 208, 507, 808, 816 |
| 2 | 104, 507, 404, 408 |
| 2 | 52, 507, 202, 204 |
| 2 | 26, 507, 101, 102 |
| 3 | 13, 507, 101, 51 |
| 13 | 13, 169, 101, 17 |
| 1, 13, 101, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 1 x 13 x 101 x 17 = 13928304
Therefore, the lowest common multiple of 208,507,808,816 is 13928304.
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 507 x 808 x 816 = 69530093568
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
507 : 1, 3, 13, 39, 169, 507
808 : 1, 2, 4, 8, 101, 202, 404, 808
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,507,808,816, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
507:3x 13x 13
808:2x 2x 2x 101
816:2x 2x 2x 2x 3x 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 2x 2x 2x 2x 2x 3x 13 = 4992
Therefore, the value for common factors is 4992.
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 = 69530093568/(1x4992)
LCM = 69530093568/4992
LCM = 13928304
Thus, we can understand that the LCM of 208,507,808,816 is 13928304.
