Given numbers are 499,428,976,765,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 499,428,976,765,638 is 12717046496880.
Find LCM of 499,428,976,765,638 with Prime Factorization
| 2 | 499, 428, 976, 765, 638 |
| 2 | 499, 214, 488, 765, 319 |
| 499, 107, 244, 765, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 499 x 107 x 244 x 765 x 319 = 12717046496880
Therefore, the lowest common multiple of 499,428,976,765,638 is 12717046496880.
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.
499 x 428 x 976 x 765 x 638 = 101736371975040
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.
499 : 1, 499
428 : 1, 2, 4, 107, 214, 428
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 499,428,976,765,638, is 1.
Now, the common factors can be found like this.
499:499
428:2x 2x 107
976:2x 2x 2x 2x 61
765:3x 3x 5x 17
638:2x 11x 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 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 101736371975040/(1x8)
LCM = 101736371975040/8
LCM = 12717046496880
Thus, we can understand that the LCM of 499,428,976,765,638 is 12717046496880.
