Given numbers are 338,212,663,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,212,663,813 is 495178788.
Find LCM of 338,212,663,813 with Prime Factorization
| 2 | 338, 212, 663, 813 |
| 3 | 169, 106, 663, 813 |
| 13 | 169, 106, 221, 271 |
| 13, 106, 17, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 13 x 106 x 17 x 271 = 495178788
Therefore, the lowest common multiple of 338,212,663,813 is 495178788.
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.
338 x 212 x 663 x 813 = 38623945464
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.
338 : 1, 2, 13, 26, 169, 338
212 : 1, 2, 4, 53, 106, 212
663 : 1, 3, 13, 17, 39, 51, 221, 663
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,212,663,813, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
212:2x 2x 53
663:3x 13x 17
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13 = 78
Therefore, the value for common factors is 78.
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 = 38623945464/(1x78)
LCM = 38623945464/78
LCM = 495178788
Thus, we can understand that the LCM of 338,212,663,813 is 495178788.
