Given numbers are 979,858,720,799
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,858,720,799 is 7321588560.
Find LCM of 979,858,720,799 with Prime Factorization
| 2 | 979, 858, 720, 799 |
| 3 | 979, 429, 360, 799 |
| 11 | 979, 143, 120, 799 |
| 89, 13, 120, 799 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 89 x 13 x 120 x 799 = 7321588560
Therefore, the lowest common multiple of 979,858,720,799 is 7321588560.
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 858 x 720 x 799 = 483224844960
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
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,858,720,799, is 1.
Now, the common factors can be found like this.
979:11x 89
858:2x 3x 11x 13
720:2x 2x 2x 2x 3x 3x 5
799:17x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 483224844960/(1x66)
LCM = 483224844960/66
LCM = 7321588560
Thus, we can understand that the LCM of 979,858,720,799 is 7321588560.
