Given numbers are 979,534,646,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,534,646,648 is 204908616.
Find LCM of 979,534,646,648 with Prime Factorization
| 2 | 979, 534, 646, 648 |
| 3 | 979, 267, 323, 324 |
| 89 | 979, 89, 323, 108 |
| 11, 1, 323, 108 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 89 x 11 x 1 x 323 x 108 = 204908616
Therefore, the lowest common multiple of 979,534,646,648 is 204908616.
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 534 x 646 x 648 = 218842401888
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
534 : 1, 2, 3, 6, 89, 178, 267, 534
646 : 1, 2, 17, 19, 34, 38, 323, 646
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,534,646,648, is 1.
Now, the common factors can be found like this.
979:11x 89
534:2x 3x 89
646:2x 17x 19
648:2x 2x 2x 3x 3x 3x 3
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 3x 89 = 1068
Therefore, the value for common factors is 1068.
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 = 218842401888/(1x1068)
LCM = 218842401888/1068
LCM = 204908616
Thus, we can understand that the LCM of 979,534,646,648 is 204908616.
