Given numbers are 558,436,682,581
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,436,682,581 is 777426804.
Find LCM of 558,436,682,581 with Prime Factorization
| 2 | 558, 436, 682, 581 |
| 31 | 279, 218, 341, 581 |
| 9, 218, 11, 581 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 9 x 218 x 11 x 581 = 777426804
Therefore, the lowest common multiple of 558,436,682,581 is 777426804.
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.
558 x 436 x 682 x 581 = 96400923696
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
436 : 1, 2, 4, 109, 218, 436
682 : 1, 2, 11, 22, 31, 62, 341, 682
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,436,682,581, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
436:2x 2x 109
682:2x 11x 31
581:7x 83
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 = 96400923696/(1x124)
LCM = 96400923696/124
LCM = 777426804
Thus, we can understand that the LCM of 558,436,682,581 is 777426804.
