Given numbers are 819,259,550,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 819,259,550,921 is 5116661550.
Find LCM of 819,259,550,921 with Prime Factorization
| 3 | 819, 259, 550, 921 |
| 7 | 273, 259, 550, 307 |
| 39, 37, 550, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 39 x 37 x 550 x 307 = 5116661550
Therefore, the lowest common multiple of 819,259,550,921 is 5116661550.
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.
819 x 259 x 550 x 921 = 107449892550
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
259 : 1, 7, 37, 259
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,259,550,921, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
259:7x 37
550:2x 5x 5x 11
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 107449892550/(1x21)
LCM = 107449892550/21
LCM = 5116661550
Thus, we can understand that the LCM of 819,259,550,921 is 5116661550.
