The LCM of 471,936,756,165 is 169729560.
Find LCM of 471,936,756,165 with Prime Factorization
| 2 | 471, 936, 756, 165 |
| 2 | 471, 468, 378, 165 |
| 3 | 471, 234, 189, 165 |
| 3 | 157, 78, 63, 55 |
| 157, 26, 21, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 157 x 26 x 21 x 55 = 169729560
Therefore, the lowest common multiple of 471,936,756,165 is 169729560.
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.
471 x 936 x 756 x 165 = 54992377440
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.
471 : 1, 3, 157, 471
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
165 : 1, 3, 5, 11, 15, 33, 55, 165
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,936,756,165, is 3.
Now, the common factors can be found like this.
471:3x 157
936:2x 2x 2x 3x 3x 13
756:2x 2x 3x 3x 3x 7
165:3x 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 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 = 54992377440/(3x108)
LCM = 54992377440/324
LCM = 169729560
Thus, we can understand that the LCM of 471,936,756,165 is 169729560.
