Given numbers are 923,559,120,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,559,120,731 is 80965560.
Find LCM of 923,559,120,731 with Prime Factorization
| 13 | 923, 559, 120, 731 |
| 43 | 71, 43, 120, 731 |
| 71, 1, 120, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 43 x 71 x 1 x 120 x 17 = 80965560
Therefore, the lowest common multiple of 923,559,120,731 is 80965560.
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.
923 x 559 x 120 x 731 = 45259748040
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.
923 : 1, 13, 71, 923
559 : 1, 13, 43, 559
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,559,120,731, is 1.
Now, the common factors can be found like this.
923:13x 71
559:13x 43
120:2x 2x 2x 3x 5
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 43 = 559
Therefore, the value for common factors is 559.
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 = 45259748040/(1x559)
LCM = 45259748040/559
LCM = 80965560
Thus, we can understand that the LCM of 923,559,120,731 is 80965560.
