Given numbers are 586,568,420,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 586,568,420,691 is 12074893320.
Find LCM of 586,568,420,691 with Prime Factorization
| 2 | 586, 568, 420, 691 |
| 2 | 293, 284, 210, 691 |
| 293, 142, 105, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 293 x 142 x 105 x 691 = 12074893320
Therefore, the lowest common multiple of 586,568,420,691 is 12074893320.
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.
586 x 568 x 420 x 691 = 96599146560
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.
586 : 1, 2, 293, 586
568 : 1, 2, 4, 8, 71, 142, 284, 568
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 586,568,420,691, is 1.
Now, the common factors can be found like this.
586:2x 293
568:2x 2x 2x 71
420:2x 2x 3x 5x 7
691:691
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 2 = 8
Therefore, the value for common factors is 8.
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 = 96599146560/(1x8)
LCM = 96599146560/8
LCM = 12074893320
Thus, we can understand that the LCM of 586,568,420,691 is 12074893320.
