Given numbers are 790,248,806,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,248,806,401 is 510665480.
Find LCM of 790,248,806,401 with Prime Factorization
| 2 | 790, 248, 806, 401 |
| 31 | 395, 124, 403, 401 |
| 395, 4, 13, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 395 x 4 x 13 x 401 = 510665480
Therefore, the lowest common multiple of 790,248,806,401 is 510665480.
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.
790 x 248 x 806 x 401 = 63322519520
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
248 : 1, 2, 4, 8, 31, 62, 124, 248
806 : 1, 2, 13, 26, 31, 62, 403, 806
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,248,806,401, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
248:2x 2x 2x 31
806:2x 13x 31
401:401
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 31 = 124
Therefore, the value for common factors is 124.
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 = 63322519520/(1x124)
LCM = 63322519520/124
LCM = 510665480
Thus, we can understand that the LCM of 790,248,806,401 is 510665480.
