Given numbers are 348,165,623,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 348,165,623,638 is 11924220.
Find LCM of 348,165,623,638 with Prime Factorization
| 2 | 348, 165, 623, 638 |
| 3 | 174, 165, 623, 319 |
| 11 | 58, 55, 623, 319 |
| 29 | 58, 5, 623, 29 |
| 2, 5, 623, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 2 x 5 x 623 x 1 = 11924220
Therefore, the lowest common multiple of 348,165,623,638 is 11924220.
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.
348 x 165 x 623 x 638 = 22822957080
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.
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
165 : 1, 3, 5, 11, 15, 33, 55, 165
623 : 1, 7, 89, 623
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 348,165,623,638, is 1.
Now, the common factors can be found like this.
348:2x 2x 3x 29
165:3x 5x 11
623:7x 89
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 29 = 1914
Therefore, the value for common factors is 1914.
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 = 22822957080/(1x1914)
LCM = 22822957080/1914
LCM = 11924220
Thus, we can understand that the LCM of 348,165,623,638 is 11924220.
