Given numbers are 476,481,442,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,481,442,768 is 43959552.
Find LCM of 476,481,442,768 with Prime Factorization
| 2 | 476, 481, 442, 768 |
| 2 | 238, 481, 221, 384 |
| 13 | 119, 481, 221, 192 |
| 17 | 119, 37, 17, 192 |
| 7, 37, 1, 192 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 7 x 37 x 1 x 192 = 43959552
Therefore, the lowest common multiple of 476,481,442,768 is 43959552.
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.
476 x 481 x 442 x 768 = 77720487936
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
481 : 1, 13, 37, 481
442 : 1, 2, 13, 17, 26, 34, 221, 442
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,481,442,768, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
481:13x 37
442:2x 13x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 13x 17 = 1768
Therefore, the value for common factors is 1768.
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 = 77720487936/(1x1768)
LCM = 77720487936/1768
LCM = 43959552
Thus, we can understand that the LCM of 476,481,442,768 is 43959552.
