The LCM of 512,840,855,942 is 481098240.
Find LCM of 512,840,855,942 with Prime Factorization
| 2 | 512, 840, 855, 942 |
| 2 | 256, 420, 855, 471 |
| 2 | 128, 210, 855, 471 |
| 3 | 64, 105, 855, 471 |
| 5 | 64, 35, 285, 157 |
| 64, 7, 57, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 64 x 7 x 57 x 157 = 481098240
Therefore, the lowest common multiple of 512,840,855,942 is 481098240.
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 840 x 855 x 942 = 346390732800
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
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,840,855,942, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
840:2x 2x 2x 3x 5x 7
855:3x 3x 5x 19
942:2x 3x 157
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 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 346390732800/(1x720)
LCM = 346390732800/720
LCM = 481098240
Thus, we can understand that the LCM of 512,840,855,942 is 481098240.
