Given numbers are 813,553,813,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,553,813,406 is 26076162.
Find LCM of 813,553,813,406 with Prime Factorization
| 3 | 813, 553, 813, 406 |
| 7 | 271, 553, 271, 406 |
| 271 | 271, 79, 271, 58 |
| 1, 79, 1, 58 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 271 x 1 x 79 x 1 x 58 = 26076162
Therefore, the lowest common multiple of 813,553,813,406 is 26076162.
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.
813 x 553 x 813 x 406 = 148399437942
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.
813 : 1, 3, 271, 813
553 : 1, 7, 79, 553
813 : 1, 3, 271, 813
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 813,553,813,406, is 1.
Now, the common factors can be found like this.
813:3x 271
553:7x 79
813:3x 271
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.
3x 7x 271 = 5691
Therefore, the value for common factors is 5691.
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 = 148399437942/(1x5691)
LCM = 148399437942/5691
LCM = 26076162
Thus, we can understand that the LCM of 813,553,813,406 is 26076162.
