Find LCM of 8,813,972,621 with Prime Factorization
| 2 | 8, 813, 972, 621 |
| 2 | 4, 813, 486, 621 |
| 3 | 2, 813, 243, 621 |
| 3 | 2, 271, 81, 207 |
| 3 | 2, 271, 27, 69 |
| 2, 271, 9, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 2 x 271 x 9 x 23 = 12116952
Therefore, the lowest common multiple of 8,813,972,621 is 12116952.
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.
8 x 813 x 972 x 621 = 3925892448
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.
8 : 1, 2, 4, 8
813 : 1, 3, 271, 813
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,813,972,621, is 1.
Now, the common factors can be found like this.
8:2x 2x 2
813:3x 271
972:2x 2x 3x 3x 3x 3x 3
621:3x 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 2x 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 3925892448/(1x324)
LCM = 3925892448/324
LCM = 12116952
Thus, we can understand that the LCM of 8,813,972,621 is 12116952.
