Given numbers are 788,642,486,559
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,642,486,559 is 11453232492.
Find LCM of 788,642,486,559 with Prime Factorization
| 2 | 788, 642, 486, 559 |
| 3 | 394, 321, 243, 559 |
| 394, 107, 81, 559 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 394 x 107 x 81 x 559 = 11453232492
Therefore, the lowest common multiple of 788,642,486,559 is 11453232492.
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.
788 x 642 x 486 x 559 = 137438789904
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.
788 : 1, 2, 4, 197, 394, 788
642 : 1, 2, 3, 6, 107, 214, 321, 642
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
559 : 1, 13, 43, 559
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,642,486,559, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
642:2x 3x 107
486:2x 3x 3x 3x 3x 3
559:13x 43
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 3 = 12
Therefore, the value for common factors is 12.
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 = 137438789904/(1x12)
LCM = 137438789904/12
LCM = 11453232492
Thus, we can understand that the LCM of 788,642,486,559 is 11453232492.
