Given numbers are 806,338,299,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 806,338,299,620 is 2409940.
Find LCM of 806,338,299,620 with Prime Factorization
| 2 | 806, 338, 299, 620 |
| 13 | 403, 169, 299, 310 |
| 31 | 31, 13, 23, 310 |
| 1, 13, 23, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 31 x 1 x 13 x 23 x 10 = 2409940
Therefore, the lowest common multiple of 806,338,299,620 is 2409940.
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.
806 x 338 x 299 x 620 = 50502702640
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.
806 : 1, 2, 13, 26, 31, 62, 403, 806
338 : 1, 2, 13, 26, 169, 338
299 : 1, 13, 23, 299
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,338,299,620, is 1.
Now, the common factors can be found like this.
806:2x 13x 31
338:2x 13x 13
299:13x 23
620:2x 2x 5x 31
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 13x 13x 31 = 20956
Therefore, the value for common factors is 20956.
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 = 50502702640/(1x20956)
LCM = 50502702640/20956
LCM = 2409940
Thus, we can understand that the LCM of 806,338,299,620 is 2409940.
