Find LCM of 543,243,778,162 with Prime Factorization
| 2 | 543, 243, 778, 162 |
| 3 | 543, 243, 389, 81 |
| 3 | 181, 27, 389, 81 |
| 3 | 181, 9, 389, 27 |
| 3 | 181, 3, 389, 9 |
| 181, 1, 389, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 181 x 1 x 389 x 3 = 34218774
Therefore, the lowest common multiple of 543,243,778,162 is 34218774.
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.
543 x 243 x 778 x 162 = 16630324164
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.
543 : 1, 3, 181, 543
243 : 1, 3, 9, 27, 81, 243
778 : 1, 2, 389, 778
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,243,778,162, is 1.
Now, the common factors can be found like this.
543:3x 181
243:3x 3x 3x 3x 3
778:2x 389
162:2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 16630324164/(1x486)
LCM = 16630324164/486
LCM = 34218774
Thus, we can understand that the LCM of 543,243,778,162 is 34218774.
