The LCM of 486,628,756,409 is 436905252.
Find LCM of 486,628,756,409 with Prime Factorization
| 2 | 486, 628, 756, 409 |
| 2 | 243, 314, 378, 409 |
| 3 | 243, 157, 189, 409 |
| 3 | 81, 157, 63, 409 |
| 3 | 27, 157, 21, 409 |
| 9, 157, 7, 409 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 9 x 157 x 7 x 409 = 436905252
Therefore, the lowest common multiple of 486,628,756,409 is 436905252.
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.
486 x 628 x 756 x 409 = 94371534432
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
628 : 1, 2, 4, 157, 314, 628
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
409 : 1, 409
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,628,756,409, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
628:2x 2x 157
756:2x 2x 3x 3x 3x 7
409:409
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 94371534432/(1x216)
LCM = 94371534432/216
LCM = 436905252
Thus, we can understand that the LCM of 486,628,756,409 is 436905252.
