Given numbers are 397,488,609,794
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,488,609,794 is 117985224.
Find LCM of 397,488,609,794 with Prime Factorization
| 2 | 397, 488, 609, 794 |
| 397 | 397, 244, 609, 397 |
| 1, 244, 609, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 397 x 1 x 244 x 609 x 1 = 117985224
Therefore, the lowest common multiple of 397,488,609,794 is 117985224.
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.
397 x 488 x 609 x 794 = 93680267856
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.
397 : 1, 397
488 : 1, 2, 4, 8, 61, 122, 244, 488
609 : 1, 3, 7, 21, 29, 87, 203, 609
794 : 1, 2, 397, 794
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,488,609,794, is 1.
Now, the common factors can be found like this.
397:397
488:2x 2x 2x 61
609:3x 7x 29
794:2x 397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 397 = 794
Therefore, the value for common factors is 794.
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 = 93680267856/(1x794)
LCM = 93680267856/794
LCM = 117985224
Thus, we can understand that the LCM of 397,488,609,794 is 117985224.
