Given numbers are 979,648,979,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,648,979,676 is 107212248.
Find LCM of 979,648,979,676 with Prime Factorization
| 2 | 979, 648, 979, 676 |
| 2 | 979, 324, 979, 338 |
| 11 | 979, 162, 979, 169 |
| 89 | 89, 162, 89, 169 |
| 1, 162, 1, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 89 x 1 x 162 x 1 x 169 = 107212248
Therefore, the lowest common multiple of 979,648,979,676 is 107212248.
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.
979 x 648 x 979 x 676 = 419843163168
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.
979 : 1, 11, 89, 979
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
979 : 1, 11, 89, 979
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,648,979,676, is 1.
Now, the common factors can be found like this.
979:11x 89
648:2x 2x 2x 3x 3x 3x 3
979:11x 89
676:2x 2x 13x 13
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 11x 89 = 3916
Therefore, the value for common factors is 3916.
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 = 419843163168/(1x3916)
LCM = 419843163168/3916
LCM = 107212248
Thus, we can understand that the LCM of 979,648,979,676 is 107212248.
