The LCM of 189,468,628,843 is 433581876.
Find LCM of 189,468,628,843 with Prime Factorization
| 2 | 189, 468, 628, 843 |
| 2 | 189, 234, 314, 843 |
| 3 | 189, 117, 157, 843 |
| 3 | 63, 39, 157, 281 |
| 21, 13, 157, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 21 x 13 x 157 x 281 = 433581876
Therefore, the lowest common multiple of 189,468,628,843 is 433581876.
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.
189 x 468 x 628 x 843 = 46826842608
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
628 : 1, 2, 4, 157, 314, 628
843 : 1, 3, 281, 843
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,468,628,843, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
468:2x 2x 3x 3x 13
628:2x 2x 157
843:3x 281
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 3 = 108
Therefore, the value for common factors is 108.
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 = 46826842608/(1x108)
LCM = 46826842608/108
LCM = 433581876
Thus, we can understand that the LCM of 189,468,628,843 is 433581876.
