The LCM of 816,399,654,476 is 11829552.
Find LCM of 816,399,654,476 with Prime Factorization
| 2 | 816, 399, 654, 476 |
| 2 | 408, 399, 327, 238 |
| 3 | 204, 399, 327, 119 |
| 7 | 68, 133, 109, 119 |
| 17 | 68, 19, 109, 17 |
| 4, 19, 109, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 17 x 4 x 19 x 109 x 1 = 11829552
Therefore, the lowest common multiple of 816,399,654,476 is 11829552.
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.
816 x 399 x 654 x 476 = 101355601536
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
399 : 1, 3, 7, 19, 21, 57, 133, 399
654 : 1, 2, 3, 6, 109, 218, 327, 654
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,399,654,476, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
399:3x 7x 19
654:2x 3x 109
476:2x 2x 7x 17
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 3x 3x 7x 17 = 8568
Therefore, the value for common factors is 8568.
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 = 101355601536/(1x8568)
LCM = 101355601536/8568
LCM = 11829552
Thus, we can understand that the LCM of 816,399,654,476 is 11829552.
