Given numbers are 338,568,169,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,568,169,685 is 65754520.
Find LCM of 338,568,169,685 with Prime Factorization
| 2 | 338, 568, 169, 685 |
| 13 | 169, 284, 169, 685 |
| 13 | 13, 284, 13, 685 |
| 1, 284, 1, 685 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 13 x 1 x 284 x 1 x 685 = 65754520
Therefore, the lowest common multiple of 338,568,169,685 is 65754520.
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.
338 x 568 x 169 x 685 = 22225027760
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.
338 : 1, 2, 13, 26, 169, 338
568 : 1, 2, 4, 8, 71, 142, 284, 568
169 : 1, 13, 169
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,568,169,685, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
568:2x 2x 2x 71
169:13x 13
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 22225027760/(1x338)
LCM = 22225027760/338
LCM = 65754520
Thus, we can understand that the LCM of 338,568,169,685 is 65754520.
