Given numbers are 359,257,957,813,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 359,257,957,813,821 is 19644996586281.
Find LCM of 359,257,957,813,821 with Prime Factorization
| 3 | 359, 257, 957, 813, 821 |
| 359, 257, 319, 271, 821 |
Multiply the prime numbers at the bottom and the left side.
3 x 359 x 257 x 319 x 271 x 821 = 19644996586281
Therefore, the lowest common multiple of 359,257,957,813,821 is 19644996586281.
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.
359 x 257 x 957 x 813 x 821 = 58934989758843
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.
359 : 1, 359
257 : 1, 257
957 : 1, 3, 11, 29, 33, 87, 319, 957
813 : 1, 3, 271, 813
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 359,257,957,813,821, is 1.
Now, the common factors can be found like this.
359:359
257:257
957:3x 11x 29
813:3x 271
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 58934989758843/(1x3)
LCM = 58934989758843/3
LCM = 19644996586281
Thus, we can understand that the LCM of 359,257,957,813,821 is 19644996586281.
