Given numbers are 844,689,646,625,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,689,646,625,871 is 7865367347500.
Find LCM of 844,689,646,625,871 with Prime Factorization
| 2 | 844, 689, 646, 625, 871 |
| 13 | 422, 689, 323, 625, 871 |
| 422, 53, 323, 625, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 422 x 53 x 323 x 625 x 67 = 7865367347500
Therefore, the lowest common multiple of 844,689,646,625,871 is 7865367347500.
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.
844 x 689 x 646 x 625 x 871 = 204499551035000
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.
844 : 1, 2, 4, 211, 422, 844
689 : 1, 13, 53, 689
646 : 1, 2, 17, 19, 34, 38, 323, 646
625 : 1, 5, 25, 125, 625
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,689,646,625,871, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
689:13x 53
646:2x 17x 19
625:5x 5x 5x 5
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 204499551035000/(1x26)
LCM = 204499551035000/26
LCM = 7865367347500
Thus, we can understand that the LCM of 844,689,646,625,871 is 7865367347500.
