Given numbers are 169,143,809,999
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,143,809,999 is 1502427069.
Find LCM of 169,143,809,999 with Prime Factorization
| 13 | 169, 143, 809, 999 |
| 13, 11, 809, 999 |
Multiply the prime numbers at the bottom and the left side.
13 x 13 x 11 x 809 x 999 = 1502427069
Therefore, the lowest common multiple of 169,143,809,999 is 1502427069.
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.
169 x 143 x 809 x 999 = 19531551897
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.
169 : 1, 13, 169
143 : 1, 11, 13, 143
809 : 1, 809
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,143,809,999, is 1.
Now, the common factors can be found like this.
169:13x 13
143:11x 13
809:809
999:3x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 19531551897/(1x13)
LCM = 19531551897/13
LCM = 1502427069
Thus, we can understand that the LCM of 169,143,809,999 is 1502427069.
