Given numbers are 213,997,168,811
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 213,997,168,811 is 9644587176.
Find LCM of 213,997,168,811 with Prime Factorization
| 3 | 213, 997, 168, 811 |
| 71, 997, 56, 811 |
Multiply the prime numbers at the bottom and the left side.
3 x 71 x 997 x 56 x 811 = 9644587176
Therefore, the lowest common multiple of 213,997,168,811 is 9644587176.
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.
213 x 997 x 168 x 811 = 28933761528
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.
213 : 1, 3, 71, 213
997 : 1, 997
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,997,168,811, is 1.
Now, the common factors can be found like this.
213:3x 71
997:997
168:2x 2x 2x 3x 7
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 28933761528/(1x3)
LCM = 28933761528/3
LCM = 9644587176
Thus, we can understand that the LCM of 213,997,168,811 is 9644587176.
