The LCM of 952,790,405,455 is 395970120.
Find LCM of 952,790,405,455 with Prime Factorization
| 2 | 952, 790, 405, 455 |
| 5 | 476, 395, 405, 455 |
| 7 | 476, 79, 81, 91 |
| 68, 79, 81, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 68 x 79 x 81 x 13 = 395970120
Therefore, the lowest common multiple of 952,790,405,455 is 395970120.
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.
952 x 790 x 405 x 455 = 138589542000
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.
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
790 : 1, 2, 5, 10, 79, 158, 395, 790
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 952,790,405,455, is 1.
Now, the common factors can be found like this.
952:2x 2x 2x 7x 17
790:2x 5x 79
405:3x 3x 3x 3x 5
455:5x 7x 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 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 138589542000/(1x350)
LCM = 138589542000/350
LCM = 395970120
Thus, we can understand that the LCM of 952,790,405,455 is 395970120.
