Given numbers are 856,631,682,874,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,631,682,874,817 is 3461046191416.
Find LCM of 856,631,682,874,817 with Prime Factorization
| 2 | 856, 631, 682, 874, 817 |
| 19 | 428, 631, 341, 437, 817 |
| 428, 631, 341, 23, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 428 x 631 x 341 x 23 x 43 = 3461046191416
Therefore, the lowest common multiple of 856,631,682,874,817 is 3461046191416.
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.
856 x 631 x 682 x 874 x 817 = 263039510547616
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
631 : 1, 631
682 : 1, 2, 11, 22, 31, 62, 341, 682
874 : 1, 2, 19, 23, 38, 46, 437, 874
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,631,682,874,817, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
631:631
682:2x 11x 31
874:2x 19x 23
817:19x 43
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 19 = 76
Therefore, the value for common factors is 76.
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 = 263039510547616/(1x76)
LCM = 263039510547616/76
LCM = 3461046191416
Thus, we can understand that the LCM of 856,631,682,874,817 is 3461046191416.
