Given numbers are 208,663,395,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 208,663,395,663 is 4190160.
Find LCM of 208,663,395,663 with Prime Factorization
| 3 | 208, 663, 395, 663 |
| 13 | 208, 221, 395, 221 |
| 17 | 16, 17, 395, 17 |
| 16, 1, 395, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 16 x 1 x 395 x 1 = 4190160
Therefore, the lowest common multiple of 208,663,395,663 is 4190160.
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 663 x 395 x 663 = 36114989040
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
663 : 1, 3, 13, 17, 39, 51, 221, 663
395 : 1, 5, 79, 395
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,663,395,663, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
663:3x 13x 17
395:5x 79
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13x 17 = 8619
Therefore, the value for common factors is 8619.
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 = 36114989040/(1x8619)
LCM = 36114989040/8619
LCM = 4190160
Thus, we can understand that the LCM of 208,663,395,663 is 4190160.
