Given numbers are 857,816,989,858,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 857,816,989,858,124 is 3065949544944.
Find LCM of 857,816,989,858,124 with Prime Factorization
| 2 | 857, 816, 989, 858, 124 |
| 2 | 857, 408, 989, 429, 62 |
| 3 | 857, 204, 989, 429, 31 |
| 857, 68, 989, 143, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 857 x 68 x 989 x 143 x 31 = 3065949544944
Therefore, the lowest common multiple of 857,816,989,858,124 is 3065949544944.
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.
857 x 816 x 989 x 858 x 124 = 73582789078656
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.
857 : 1, 857
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
989 : 1, 23, 43, 989
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,816,989,858,124, is 1.
Now, the common factors can be found like this.
857:857
816:2x 2x 2x 2x 3x 17
989:23x 43
858:2x 3x 11x 13
124:2x 2x 31
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 73582789078656/(1x24)
LCM = 73582789078656/24
LCM = 3065949544944
Thus, we can understand that the LCM of 857,816,989,858,124 is 3065949544944.
