Given numbers are 105,660,454,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,660,454,928 is 243307680.
Find LCM of 105,660,454,928 with Prime Factorization
| 2 | 105, 660, 454, 928 |
| 2 | 105, 330, 227, 464 |
| 3 | 105, 165, 227, 232 |
| 5 | 35, 55, 227, 232 |
| 7, 11, 227, 232 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 227 x 232 = 243307680
Therefore, the lowest common multiple of 105,660,454,928 is 243307680.
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.
105 x 660 x 454 x 928 = 29196921600
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
454 : 1, 2, 227, 454
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 105,660,454,928, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
660:2x 2x 3x 5x 11
454:2x 227
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 29196921600/(1x120)
LCM = 29196921600/120
LCM = 243307680
Thus, we can understand that the LCM of 105,660,454,928 is 243307680.
