Given numbers are 577,831,731,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 577,831,731,387 is 1051514991.
Find LCM of 577,831,731,387 with Prime Factorization
| 3 | 577, 831, 731, 387 |
| 43 | 577, 277, 731, 129 |
| 577, 277, 17, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 577 x 277 x 17 x 3 = 1051514991
Therefore, the lowest common multiple of 577,831,731,387 is 1051514991.
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.
577 x 831 x 731 x 387 = 135645433839
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.
577 : 1, 577
831 : 1, 3, 277, 831
731 : 1, 17, 43, 731
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,831,731,387, is 1.
Now, the common factors can be found like this.
577:577
831:3x 277
731:17x 43
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 135645433839/(1x129)
LCM = 135645433839/129
LCM = 1051514991
Thus, we can understand that the LCM of 577,831,731,387 is 1051514991.
