Find LCM of 378,411,393,864,126 with Prime Factorization
| 2 | 378, 411, 393, 864, 126 |
| 3 | 189, 411, 393, 432, 63 |
| 3 | 21, 137, 131, 144, 63 |
| 3 | 7, 137, 131, 48, 21 |
| 7 | 7, 137, 131, 16, 7 |
| 1, 137, 131, 16, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 1 x 137 x 131 x 16 x 1 = 108543456
Therefore, the lowest common multiple of 378,411,393,864,126 is 108543456.
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.
378 x 411 x 393 x 864 x 126 = 6646767071616
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
411 : 1, 3, 137, 411
393 : 1, 3, 131, 393
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,411,393,864,126, is 3.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
411:3x 137
393:3x 131
864:2x 2x 2x 2x 2x 3x 3x 3
126:2x 3x 3x 7
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 3x 3x 3x 3x 3x 3x 7 = 20412
Therefore, the value for common factors is 20412.
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 = 6646767071616/(3x20412)
LCM = 6646767071616/61236
LCM = 108543456
Thus, we can understand that the LCM of 378,411,393,864,126 is 108543456.
