Given numbers are 344,860,861,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 344,860,861,817 is 28137480.
Find LCM of 344,860,861,817 with Prime Factorization
| 2 | 344, 860, 861, 817 |
| 2 | 172, 430, 861, 817 |
| 43 | 86, 215, 861, 817 |
| 2, 5, 861, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 2 x 5 x 861 x 19 = 28137480
Therefore, the lowest common multiple of 344,860,861,817 is 28137480.
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.
344 x 860 x 861 x 817 = 208104802080
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.
344 : 1, 2, 4, 8, 43, 86, 172, 344
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
861 : 1, 3, 7, 21, 41, 123, 287, 861
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,860,861,817, is 1.
Now, the common factors can be found like this.
344:2x 2x 2x 43
860:2x 2x 5x 43
861:3x 7x 41
817:19x 43
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 43x 43 = 7396
Therefore, the value for common factors is 7396.
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 = 208104802080/(1x7396)
LCM = 208104802080/7396
LCM = 28137480
Thus, we can understand that the LCM of 344,860,861,817 is 28137480.
