Given numbers are 814,434,806,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,434,806,457 is 1049406358.
Find LCM of 814,434,806,457 with Prime Factorization
| 2 | 814, 434, 806, 457 |
| 31 | 407, 217, 403, 457 |
| 407, 7, 13, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 407 x 7 x 13 x 457 = 1049406358
Therefore, the lowest common multiple of 814,434,806,457 is 1049406358.
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.
814 x 434 x 806 x 457 = 130126388392
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
434 : 1, 2, 7, 14, 31, 62, 217, 434
806 : 1, 2, 13, 26, 31, 62, 403, 806
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,434,806,457, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
434:2x 7x 31
806:2x 13x 31
457:457
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 31 = 124
Therefore, the value for common factors is 124.
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 = 130126388392/(1x124)
LCM = 130126388392/124
LCM = 1049406358
Thus, we can understand that the LCM of 814,434,806,457 is 1049406358.
