Given numbers are 813,651,559,344
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,651,559,344 is 788954712.
Find LCM of 813,651,559,344 with Prime Factorization
| 3 | 813, 651, 559, 344 |
| 43 | 271, 217, 559, 344 |
| 271, 217, 13, 8 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 271 x 217 x 13 x 8 = 788954712
Therefore, the lowest common multiple of 813,651,559,344 is 788954712.
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 651 x 559 x 344 = 101775157848
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
651 : 1, 3, 7, 21, 31, 93, 217, 651
559 : 1, 13, 43, 559
344 : 1, 2, 4, 8, 43, 86, 172, 344
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,651,559,344, is 1.
Now, the common factors can be found like this.
813:3x 271
651:3x 7x 31
559:13x 43
344:2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 101775157848/(1x129)
LCM = 101775157848/129
LCM = 788954712
Thus, we can understand that the LCM of 813,651,559,344 is 788954712.
