Find LCM of 471,405,538,812,684 with Prime Factorization
| 2 | 471, 405, 538, 812, 684 |
| 2 | 471, 405, 269, 406, 342 |
| 3 | 471, 405, 269, 203, 171 |
| 3 | 157, 135, 269, 203, 57 |
| 157, 45, 269, 203, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 157 x 45 x 269 x 203 x 19 = 263886143220
Therefore, the lowest common multiple of 471,405,538,812,684 is 263886143220.
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.
471 x 405 x 538 x 812 x 684 = 56999406935520
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.
471 : 1, 3, 157, 471
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
538 : 1, 2, 269, 538
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,405,538,812,684, is 1.
Now, the common factors can be found like this.
471:3x 157
405:3x 3x 3x 3x 5
538:2x 269
812:2x 2x 7x 29
684:2x 2x 3x 3x 19
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 3 = 216
Therefore, the value for common factors is 216.
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 = 56999406935520/(1x216)
LCM = 56999406935520/216
LCM = 263886143220
Thus, we can understand that the LCM of 471,405,538,812,684 is 263886143220.
