The LCM of 165,689,305,143,406 is 2815522710.
Find LCM of 165,689,305,143,406 with Prime Factorization
| 5 | 165, 689, 305, 143, 406 |
| 11 | 33, 689, 61, 143, 406 |
| 13 | 3, 689, 61, 13, 406 |
| 3, 53, 61, 1, 406 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 3 x 53 x 61 x 1 x 406 = 2815522710
Therefore, the lowest common multiple of 165,689,305,143,406 is 2815522710.
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.
165 x 689 x 305 x 143 x 406 = 2013098737650
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
689 : 1, 13, 53, 689
305 : 1, 5, 61, 305
143 : 1, 11, 13, 143
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,689,305,143,406, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
689:13x 53
305:5x 61
143:11x 13
406:2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 13 = 715
Therefore, the value for common factors is 715.
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 = 2013098737650/(1x715)
LCM = 2013098737650/715
LCM = 2815522710
Thus, we can understand that the LCM of 165,689,305,143,406 is 2815522710.
