Given numbers are 382,968,928,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 382,968,928,920 is 2466405920.
Find LCM of 382,968,928,920 with Prime Factorization
| 2 | 382, 968, 928, 920 |
| 2 | 191, 484, 464, 460 |
| 2 | 191, 242, 232, 230 |
| 191, 121, 116, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 191 x 121 x 116 x 115 = 2466405920
Therefore, the lowest common multiple of 382,968,928,920 is 2466405920.
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.
382 x 968 x 928 x 920 = 315699957760
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.
382 : 1, 2, 191, 382
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 382,968,928,920, is 2.
Now, the common factors can be found like this.
382:2x 191
968:2x 2x 2x 11x 11
928:2x 2x 2x 2x 2x 29
920:2x 2x 2x 5x 23
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 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 315699957760/(2x64)
LCM = 315699957760/128
LCM = 2466405920
Thus, we can understand that the LCM of 382,968,928,920 is 2466405920.
