Find LCM of 811,291,622,120,872 with Prime Factorization
| 2 | 811, 291, 622, 120, 872 |
| 2 | 811, 291, 311, 60, 436 |
| 2 | 811, 291, 311, 30, 218 |
| 3 | 811, 291, 311, 15, 109 |
| 811, 97, 311, 5, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 811 x 97 x 311 x 5 x 109 = 320007915960
Therefore, the lowest common multiple of 811,291,622,120,872 is 320007915960.
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.
811 x 291 x 622 x 120 x 872 = 15360379966080
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.
811 : 1, 811
291 : 1, 3, 97, 291
622 : 1, 2, 311, 622
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,291,622,120,872, is 1.
Now, the common factors can be found like this.
811:811
291:3x 97
622:2x 311
120:2x 2x 2x 3x 5
872:2x 2x 2x 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 3 = 48
Therefore, the value for common factors is 48.
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 = 15360379966080/(1x48)
LCM = 15360379966080/48
LCM = 320007915960
Thus, we can understand that the LCM of 811,291,622,120,872 is 320007915960.
