Find LCM of 307,921,751,837,405 with Prime Factorization
| 3 | 307, 921, 751, 837, 405 |
| 3 | 307, 307, 751, 279, 135 |
| 3 | 307, 307, 751, 93, 45 |
| 307 | 307, 307, 751, 31, 15 |
| 1, 1, 751, 31, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 307 x 1 x 1 x 751 x 31 x 15 = 2894643135
Therefore, the lowest common multiple of 307,921,751,837,405 is 2894643135.
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.
307 x 921 x 751 x 837 x 405 = 71981090838045
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.
307 : 1, 307
921 : 1, 3, 307, 921
751 : 1, 751
837 : 1, 3, 9, 27, 31, 93, 279, 837
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,921,751,837,405, is 1.
Now, the common factors can be found like this.
307:307
921:3x 307
751:751
837:3x 3x 3x 31
405:3x 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 307 = 24867
Therefore, the value for common factors is 24867.
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 = 71981090838045/(1x24867)
LCM = 71981090838045/24867
LCM = 2894643135
Thus, we can understand that the LCM of 307,921,751,837,405 is 2894643135.
