Given numbers are 512,486,585,783
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 512,486,585,783 is 234524160.
Find LCM of 512,486,585,783 with Prime Factorization
| 2 | 512, 486, 585, 783 |
| 3 | 256, 243, 585, 783 |
| 3 | 256, 81, 195, 261 |
| 3 | 256, 27, 65, 87 |
| 256, 9, 65, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 256 x 9 x 65 x 29 = 234524160
Therefore, the lowest common multiple of 512,486,585,783 is 234524160.
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.
512 x 486 x 585 x 783 = 113978741760
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,486,585,783, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
486:2x 3x 3x 3x 3x 3
585:3x 3x 5x 13
783:3x 3x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 113978741760/(1x486)
LCM = 113978741760/486
LCM = 234524160
Thus, we can understand that the LCM of 512,486,585,783 is 234524160.
