Find LCM of 162,309,891,486,550 with Prime Factorization
| 2 | 162, 309, 891, 486, 550 |
| 3 | 81, 309, 891, 243, 275 |
| 3 | 27, 103, 297, 81, 275 |
| 3 | 9, 103, 99, 27, 275 |
| 3 | 3, 103, 33, 9, 275 |
| 11 | 1, 103, 11, 3, 275 |
| 1, 103, 1, 3, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 11 x 1 x 103 x 1 x 3 x 25 = 13765950
Therefore, the lowest common multiple of 162,309,891,486,550 is 13765950.
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.
162 x 309 x 891 x 486 x 550 = 11922028529400
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
309 : 1, 3, 103, 309
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,309,891,486,550, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
309:3x 103
891:3x 3x 3x 3x 11
486:2x 3x 3x 3x 3x 3
550:2x 5x 5x 11
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 3x 3x 3x 3x 3x 3x 11 = 866052
Therefore, the value for common factors is 866052.
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 = 11922028529400/(1x866052)
LCM = 11922028529400/866052
LCM = 13765950
Thus, we can understand that the LCM of 162,309,891,486,550 is 13765950.
