Find LCM of 808,672,505,654 with Prime Factorization
| 2 | 808, 672, 505, 654 |
| 2 | 404, 336, 505, 327 |
| 2 | 202, 168, 505, 327 |
| 3 | 101, 84, 505, 327 |
| 101 | 101, 28, 505, 109 |
| 1, 28, 5, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 101 x 1 x 28 x 5 x 109 = 36990240
Therefore, the lowest common multiple of 808,672,505,654 is 36990240.
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.
808 x 672 x 505 x 654 = 179328683520
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
505 : 1, 5, 101, 505
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,672,505,654, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
672:2x 2x 2x 2x 2x 3x 7
505:5x 101
654:2x 3x 109
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 101 = 4848
Therefore, the value for common factors is 4848.
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 = 179328683520/(1x4848)
LCM = 179328683520/4848
LCM = 36990240
Thus, we can understand that the LCM of 808,672,505,654 is 36990240.
