Given numbers are 717,394,788,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,394,788,928 is 131079072.
Find LCM of 717,394,788,928 with Prime Factorization
| 2 | 717, 394, 788, 928 |
| 2 | 717, 197, 394, 464 |
| 197 | 717, 197, 197, 232 |
| 717, 1, 1, 232 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 197 x 717 x 1 x 1 x 232 = 131079072
Therefore, the lowest common multiple of 717,394,788,928 is 131079072.
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.
717 x 394 x 788 x 928 = 206580617472
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.
717 : 1, 3, 239, 717
394 : 1, 2, 197, 394
788 : 1, 2, 4, 197, 394, 788
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 717,394,788,928, is 1.
Now, the common factors can be found like this.
717:3x 239
394:2x 197
788:2x 2x 197
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 2x 2x 197 = 1576
Therefore, the value for common factors is 1576.
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 = 206580617472/(1x1576)
LCM = 206580617472/1576
LCM = 131079072
Thus, we can understand that the LCM of 717,394,788,928 is 131079072.
