Given numbers are 586,820,460,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 586,820,460,989 is 237617140.
Find LCM of 586,820,460,989 with Prime Factorization
| 2 | 586, 820, 460, 989 |
| 2 | 293, 410, 230, 989 |
| 5 | 293, 205, 115, 989 |
| 23 | 293, 41, 23, 989 |
| 293, 41, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 293 x 41 x 1 x 43 = 237617140
Therefore, the lowest common multiple of 586,820,460,989 is 237617140.
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 820 x 460 x 989 = 218607768800
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
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 586,820,460,989, is 1.
Now, the common factors can be found like this.
586:2x 293
820:2x 2x 5x 41
460:2x 2x 5x 23
989:23x 43
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 2x 5x 23 = 920
Therefore, the value for common factors is 920.
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 = 218607768800/(1x920)
LCM = 218607768800/920
LCM = 237617140
Thus, we can understand that the LCM of 586,820,460,989 is 237617140.
