Given numbers are 790,294,352,343,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,294,352,343,811 is 116031521760.
Find LCM of 790,294,352,343,811 with Prime Factorization
| 2 | 790, 294, 352, 343, 811 |
| 7 | 395, 147, 176, 343, 811 |
| 7 | 395, 21, 176, 49, 811 |
| 395, 3, 176, 7, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 395 x 3 x 176 x 7 x 811 = 116031521760
Therefore, the lowest common multiple of 790,294,352,343,811 is 116031521760.
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 294 x 352 x 343 x 811 = 22742178264960
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
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
343 : 1, 7, 49, 343
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,294,352,343,811, is 1.
Now, the common factors can be found like this.
790:2x 5x 79
294:2x 3x 7x 7
352:2x 2x 2x 2x 2x 11
343:7x 7x 7
811:811
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 22742178264960/(1x196)
LCM = 22742178264960/196
LCM = 116031521760
Thus, we can understand that the LCM of 790,294,352,343,811 is 116031521760.
