Given numbers are 731,387,731,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,387,731,559 is 85527.
Find LCM of 731,387,731,559 with Prime Factorization
17 | 731, 387, 731, 559 |
43 | 43, 387, 43, 559 |
1, 9, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
17 x 43 x 1 x 9 x 1 x 13 = 85527
Therefore, the lowest common multiple of 731,387,731,559 is 85527.
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.
731 x 387 x 731 x 559 = 115599918213
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.
731 : 1, 17, 43, 731
387 : 1, 3, 9, 43, 129, 387
731 : 1, 17, 43, 731
559 : 1, 13, 43, 559
43 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,387,731,559, is 43.
Now, the common factors can be found like this.
731:17x 43
387:3x 3x 43
731:17x 43
559:13x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 43x 43 = 31433
Therefore, the value for common factors is 31433.
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 = 115599918213/(43x31433)
LCM = 115599918213/1351619
LCM = 85527
Thus, we can understand that the LCM of 731,387,731,559 is 85527.
