Given numbers are 126,780,926,311,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,780,926,311,724 is 426907566540.
Find LCM of 126,780,926,311,724 with Prime Factorization
| 2 | 126, 780, 926, 311, 724 |
| 2 | 63, 390, 463, 311, 362 |
| 3 | 63, 195, 463, 311, 181 |
| 21, 65, 463, 311, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 21 x 65 x 463 x 311 x 181 = 426907566540
Therefore, the lowest common multiple of 126,780,926,311,724 is 426907566540.
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.
126 x 780 x 926 x 311 x 724 = 20491563193920
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
926 : 1, 2, 463, 926
311 : 1, 311
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,780,926,311,724, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
780:2x 2x 3x 5x 13
926:2x 463
311:311
724:2x 2x 181
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 3 = 48
Therefore, the value for common factors is 48.
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 = 20491563193920/(1x48)
LCM = 20491563193920/48
LCM = 426907566540
Thus, we can understand that the LCM of 126,780,926,311,724 is 426907566540.
