Given numbers are 638,797,591,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,797,591,580 is 3005152260.
Find LCM of 638,797,591,580 with Prime Factorization
| 2 | 638, 797, 591, 580 |
| 29 | 319, 797, 591, 290 |
| 11, 797, 591, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 11 x 797 x 591 x 10 = 3005152260
Therefore, the lowest common multiple of 638,797,591,580 is 3005152260.
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.
638 x 797 x 591 x 580 = 174298831080
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
797 : 1, 797
591 : 1, 3, 197, 591
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,797,591,580, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
797:797
591:3x 197
580:2x 2x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 29 = 58
Therefore, the value for common factors is 58.
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 = 174298831080/(1x58)
LCM = 174298831080/58
LCM = 3005152260
Thus, we can understand that the LCM of 638,797,591,580 is 3005152260.
