Given numbers are 837,921,806,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 837,921,806,979 is 6540634386.
Find LCM of 837,921,806,979 with Prime Factorization
| 3 | 837, 921, 806, 979 |
| 31 | 279, 307, 806, 979 |
| 9, 307, 26, 979 |
Multiply the prime numbers at the bottom and the left side.
3 x 31 x 9 x 307 x 26 x 979 = 6540634386
Therefore, the lowest common multiple of 837,921,806,979 is 6540634386.
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.
837 x 921 x 806 x 979 = 608278997898
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.
837 : 1, 3, 9, 27, 31, 93, 279, 837
921 : 1, 3, 307, 921
806 : 1, 2, 13, 26, 31, 62, 403, 806
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,921,806,979, is 1.
Now, the common factors can be found like this.
837:3x 3x 3x 31
921:3x 307
806:2x 13x 31
979:11x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 31 = 93
Therefore, the value for common factors is 93.
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 = 608278997898/(1x93)
LCM = 608278997898/93
LCM = 6540634386
Thus, we can understand that the LCM of 837,921,806,979 is 6540634386.
