Given numbers are 565,561,571,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 565,561,571,731 is 7782441645.
Find LCM of 565,561,571,731 with Prime Factorization
| 17 | 565, 561, 571, 731 |
| 565, 33, 571, 43 |
Multiply the prime numbers at the bottom and the left side.
17 x 565 x 33 x 571 x 43 = 7782441645
Therefore, the lowest common multiple of 565,561,571,731 is 7782441645.
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.
565 x 561 x 571 x 731 = 132301507965
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.
565 : 1, 5, 113, 565
561 : 1, 3, 11, 17, 33, 51, 187, 561
571 : 1, 571
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,561,571,731, is 1.
Now, the common factors can be found like this.
565:5x 113
561:3x 11x 17
571:571
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.
17 = 17
Therefore, the value for common factors is 17.
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 = 132301507965/(1x17)
LCM = 132301507965/17
LCM = 7782441645
Thus, we can understand that the LCM of 565,561,571,731 is 7782441645.
