Find LCM of 405,523,991,885,540 with Prime Factorization
| 3 | 405, 523, 991, 885, 540 |
| 3 | 135, 523, 991, 295, 180 |
| 3 | 45, 523, 991, 295, 60 |
| 5 | 15, 523, 991, 295, 20 |
| 3, 523, 991, 59, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 3 x 523 x 991 x 59 x 4 = 49538444940
Therefore, the lowest common multiple of 405,523,991,885,540 is 49538444940.
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 523 x 991 x 885 x 540 = 100315351003500
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
523 : 1, 523
991 : 1, 991
885 : 1, 3, 5, 15, 59, 177, 295, 885
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,523,991,885,540, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
523:523
991:991
885:3x 5x 59
540:2x 2x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 5 = 2025
Therefore, the value for common factors is 2025.
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 = 100315351003500/(1x2025)
LCM = 100315351003500/2025
LCM = 49538444940
Thus, we can understand that the LCM of 405,523,991,885,540 is 49538444940.
