Given numbers are 793,451,638,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 793,451,638,928 is 331892704.
Find LCM of 793,451,638,928 with Prime Factorization
| 2 | 793, 451, 638, 928 |
| 11 | 793, 451, 319, 464 |
| 29 | 793, 41, 29, 464 |
| 793, 41, 1, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 793 x 41 x 1 x 16 = 331892704
Therefore, the lowest common multiple of 793,451,638,928 is 331892704.
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.
793 x 451 x 638 x 928 = 211747545152
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.
793 : 1, 13, 61, 793
451 : 1, 11, 41, 451
638 : 1, 2, 11, 22, 29, 58, 319, 638
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,451,638,928, is 1.
Now, the common factors can be found like this.
793:13x 61
451:11x 41
638:2x 11x 29
928:2x 2x 2x 2x 2x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 29 = 638
Therefore, the value for common factors is 638.
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 = 211747545152/(1x638)
LCM = 211747545152/638
LCM = 331892704
Thus, we can understand that the LCM of 793,451,638,928 is 331892704.
