Find LCM of 405,238,872,805,207 with Prime Factorization
| 2 | 405, 238, 872, 805, 207 |
| 3 | 405, 119, 436, 805, 207 |
| 3 | 135, 119, 436, 805, 69 |
| 5 | 45, 119, 436, 805, 23 |
| 7 | 9, 119, 436, 161, 23 |
| 23 | 9, 17, 436, 23, 23 |
| 9, 17, 436, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 23 x 9 x 17 x 436 x 1 x 1 = 966598920
Therefore, the lowest common multiple of 405,238,872,805,207 is 966598920.
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.
405 x 238 x 872 x 805 x 207 = 14006018350800
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
238 : 1, 2, 7, 14, 17, 34, 119, 238
872 : 1, 2, 4, 8, 109, 218, 436, 872
805 : 1, 5, 7, 23, 35, 115, 161, 805
207 : 1, 3, 9, 23, 69, 207
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,238,872,805,207, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
238:2x 7x 17
872:2x 2x 2x 109
805:5x 7x 23
207:3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 7x 23 = 14490
Therefore, the value for common factors is 14490.
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 = 14006018350800/(1x14490)
LCM = 14006018350800/14490
LCM = 966598920
Thus, we can understand that the LCM of 405,238,872,805,207 is 966598920.
