Given numbers are 439,705,477,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 439,705,477,891 is 4871760795.
Find LCM of 439,705,477,891 with Prime Factorization
| 3 | 439, 705, 477, 891 |
| 3 | 439, 235, 159, 297 |
| 439, 235, 53, 99 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 439 x 235 x 53 x 99 = 4871760795
Therefore, the lowest common multiple of 439,705,477,891 is 4871760795.
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.
439 x 705 x 477 x 891 = 131537541465
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.
439 : 1, 439
705 : 1, 3, 5, 15, 47, 141, 235, 705
477 : 1, 3, 9, 53, 159, 477
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,705,477,891, is 1.
Now, the common factors can be found like this.
439:439
705:3x 5x 47
477:3x 3x 53
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3 = 27
Therefore, the value for common factors is 27.
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 = 131537541465/(1x27)
LCM = 131537541465/27
LCM = 4871760795
Thus, we can understand that the LCM of 439,705,477,891 is 4871760795.
