Given numbers are 139,389,309,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,389,309,389 is 16707939.
Find LCM of 139,389,309,389 with Prime Factorization
| 389 | 139, 389, 309, 389 |
| 139, 1, 309, 1 |
Multiply the prime numbers at the bottom and the left side.
389 x 139 x 1 x 309 x 1 = 16707939
Therefore, the lowest common multiple of 139,389,309,389 is 16707939.
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.
139 x 389 x 309 x 389 = 6499388271
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.
139 : 1, 139
389 : 1, 389
309 : 1, 3, 103, 309
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,389,309,389, is 1.
Now, the common factors can be found like this.
139:139
389:389
309:3x 103
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
389 = 389
Therefore, the value for common factors is 389.
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 = 6499388271/(1x389)
LCM = 6499388271/389
LCM = 16707939
Thus, we can understand that the LCM of 139,389,309,389 is 16707939.
