Find LCM of 396,807,872,216,457 with Prime Factorization
| 2 | 396, 807, 872, 216, 457 |
| 2 | 198, 807, 436, 108, 457 |
| 2 | 99, 807, 218, 54, 457 |
| 3 | 99, 807, 109, 27, 457 |
| 3 | 33, 269, 109, 9, 457 |
| 11, 269, 109, 3, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 11 x 269 x 109 x 3 x 457 = 31837680072
Therefore, the lowest common multiple of 396,807,872,216,457 is 31837680072.
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.
396 x 807 x 872 x 216 x 457 = 27507755582208
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
807 : 1, 3, 269, 807
872 : 1, 2, 4, 8, 109, 218, 436, 872
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,807,872,216,457, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
807:3x 269
872:2x 2x 2x 109
216:2x 2x 2x 3x 3x 3
457:457
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 2x 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 27507755582208/(1x864)
LCM = 27507755582208/864
LCM = 31837680072
Thus, we can understand that the LCM of 396,807,872,216,457 is 31837680072.
