Given numbers are 790,999,997,816,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,999,997,816,242 is 12948278040720.
Find LCM of 790,999,997,816,242 with Prime Factorization
| 2 | 790, 999, 997, 816, 242 |
| 3 | 395, 999, 997, 408, 121 |
| 395, 333, 997, 136, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 395 x 333 x 997 x 136 x 121 = 12948278040720
Therefore, the lowest common multiple of 790,999,997,816,242 is 12948278040720.
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.
790 x 999 x 997 x 816 x 242 = 155379336488640
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
999 : 1, 3, 9, 27, 37, 111, 333, 999
997 : 1, 997
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,999,997,816,242, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
999:3x 3x 3x 37
997:997
816:2x 2x 2x 2x 3x 17
242:2x 11x 11
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 3 = 12
Therefore, the value for common factors is 12.
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 = 155379336488640/(1x12)
LCM = 155379336488640/12
LCM = 12948278040720
Thus, we can understand that the LCM of 790,999,997,816,242 is 12948278040720.
