The LCM of 816,172,740,344,664 is 538776240.
Find LCM of 816,172,740,344,664 with Prime Factorization
| 2 | 816, 172, 740, 344, 664 |
| 2 | 408, 86, 370, 172, 332 |
| 2 | 204, 43, 185, 86, 166 |
| 43 | 102, 43, 185, 43, 83 |
| 102, 1, 185, 1, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 43 x 102 x 1 x 185 x 1 x 83 = 538776240
Therefore, the lowest common multiple of 816,172,740,344,664 is 538776240.
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.
816 x 172 x 740 x 344 x 664 = 23723395399680
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
172 : 1, 2, 4, 43, 86, 172
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
344 : 1, 2, 4, 8, 43, 86, 172, 344
664 : 1, 2, 4, 8, 83, 166, 332, 664
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,172,740,344,664, is 4.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
172:2x 2x 43
740:2x 2x 5x 37
344:2x 2x 2x 43
664:2x 2x 2x 83
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 2x 2x 2x 2x 2x 2x 43 = 11008
Therefore, the value for common factors is 11008.
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 = 23723395399680/(4x11008)
LCM = 23723395399680/44032
LCM = 538776240
Thus, we can understand that the LCM of 816,172,740,344,664 is 538776240.
