Given numbers are 399,813,845,271
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,813,845,271 is 91369005.
Find LCM of 399,813,845,271 with Prime Factorization
| 3 | 399, 813, 845, 271 |
| 271 | 133, 271, 845, 271 |
| 133, 1, 845, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 271 x 133 x 1 x 845 x 1 = 91369005
Therefore, the lowest common multiple of 399,813,845,271 is 91369005.
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.
399 x 813 x 845 x 271 = 74283001065
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
813 : 1, 3, 271, 813
845 : 1, 5, 13, 65, 169, 845
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,813,845,271, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
813:3x 271
845:5x 13x 13
271:271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 271 = 813
Therefore, the value for common factors is 813.
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 = 74283001065/(1x813)
LCM = 74283001065/813
LCM = 91369005
Thus, we can understand that the LCM of 399,813,845,271 is 91369005.
