Given numbers are 512,612,387,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 512,612,387,728 is 306528768.
Find LCM of 512,612,387,728 with Prime Factorization
| 2 | 512, 612, 387, 728 |
| 2 | 256, 306, 387, 364 |
| 2 | 128, 153, 387, 182 |
| 3 | 64, 153, 387, 91 |
| 3 | 64, 51, 129, 91 |
| 64, 17, 43, 91 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 64 x 17 x 43 x 91 = 306528768
Therefore, the lowest common multiple of 512,612,387,728 is 306528768.
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 612 x 387 x 728 = 88280285184
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
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
387 : 1, 3, 9, 43, 129, 387
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,612,387,728, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
612:2x 2x 3x 3x 17
387:3x 3x 43
728:2x 2x 2x 7x 13
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 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 88280285184/(1x288)
LCM = 88280285184/288
LCM = 306528768
Thus, we can understand that the LCM of 512,612,387,728 is 306528768.
