Given numbers are 833,154,245,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 833,154,245,857 is 78526910.
Find LCM of 833,154,245,857 with Prime Factorization
| 7 | 833, 154, 245, 857 |
| 7 | 119, 22, 35, 857 |
| 17, 22, 5, 857 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 17 x 22 x 5 x 857 = 78526910
Therefore, the lowest common multiple of 833,154,245,857 is 78526910.
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.
833 x 154 x 245 x 857 = 26934730130
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.
833 : 1, 7, 17, 49, 119, 833
154 : 1, 2, 7, 11, 14, 22, 77, 154
245 : 1, 5, 7, 35, 49, 245
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,154,245,857, is 1.
Now, the common factors can be found like this.
833:7x 7x 17
154:2x 7x 11
245:5x 7x 7
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 7 = 343
Therefore, the value for common factors is 343.
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 = 26934730130/(1x343)
LCM = 26934730130/343
LCM = 78526910
Thus, we can understand that the LCM of 833,154,245,857 is 78526910.
