Given numbers are 811,243,394,310,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,243,394,310,790 is 950784600690.
Find LCM of 811,243,394,310,790 with Prime Factorization
| 2 | 811, 243, 394, 310, 790 |
| 5 | 811, 243, 197, 155, 395 |
| 811, 243, 197, 31, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 811 x 243 x 197 x 31 x 79 = 950784600690
Therefore, the lowest common multiple of 811,243,394,310,790 is 950784600690.
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.
811 x 243 x 394 x 310 x 790 = 19015692013800
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.
811 : 1, 811
243 : 1, 3, 9, 27, 81, 243
394 : 1, 2, 197, 394
310 : 1, 2, 5, 10, 31, 62, 155, 310
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,243,394,310,790, is 1.
Now, the common factors can be found like this.
811:811
243:3x 3x 3x 3x 3
394:2x 197
310:2x 5x 31
790:2x 5x 79
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 5 = 20
Therefore, the value for common factors is 20.
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 = 19015692013800/(1x20)
LCM = 19015692013800/20
LCM = 950784600690
Thus, we can understand that the LCM of 811,243,394,310,790 is 950784600690.
