Given numbers are 775,535,786,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,535,786,961 is 2020550550.
Find LCM of 775,535,786,961 with Prime Factorization
| 5 | 775, 535, 786, 961 |
| 31 | 155, 107, 786, 961 |
| 5, 107, 786, 31 |
Multiply the prime numbers at the bottom and the left side.
5 x 31 x 5 x 107 x 786 x 31 = 2020550550
Therefore, the lowest common multiple of 775,535,786,961 is 2020550550.
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.
775 x 535 x 786 x 961 = 313185335250
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.
775 : 1, 5, 25, 31, 155, 775
535 : 1, 5, 107, 535
786 : 1, 2, 3, 6, 131, 262, 393, 786
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,535,786,961, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
535:5x 107
786:2x 3x 131
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 31 = 155
Therefore, the value for common factors is 155.
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 = 313185335250/(1x155)
LCM = 313185335250/155
LCM = 2020550550
Thus, we can understand that the LCM of 775,535,786,961 is 2020550550.
