Given numbers are 729,906,474,792
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,906,474,792 is 765269208.
Find LCM of 729,906,474,792 with Prime Factorization
| 2 | 729, 906, 474, 792 |
| 3 | 729, 453, 237, 396 |
| 3 | 243, 151, 79, 132 |
| 81, 151, 79, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 81 x 151 x 79 x 44 = 765269208
Therefore, the lowest common multiple of 729,906,474,792 is 765269208.
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.
729 x 906 x 474 x 792 = 247947223392
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.
729 : 1, 3, 9, 27, 81, 243, 729
906 : 1, 2, 3, 6, 151, 302, 453, 906
474 : 1, 2, 3, 6, 79, 158, 237, 474
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,906,474,792, is 3.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
906:2x 3x 151
474:2x 3x 79
792:2x 2x 2x 3x 3x 11
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 247947223392/(3x108)
LCM = 247947223392/324
LCM = 765269208
Thus, we can understand that the LCM of 729,906,474,792 is 765269208.
