Given numbers are 439,783,686,138,439
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 439,783,686,138,439 is 5423482386.
Find LCM of 439,783,686,138,439 with Prime Factorization
| 2 | 439, 783, 686, 138, 439 |
| 3 | 439, 783, 343, 69, 439 |
| 439 | 439, 261, 343, 23, 439 |
| 1, 261, 343, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 439 x 1 x 261 x 343 x 23 x 1 = 5423482386
Therefore, the lowest common multiple of 439,783,686,138,439 is 5423482386.
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 783 x 686 x 138 x 439 = 14285452604724
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
783 : 1, 3, 9, 27, 29, 87, 261, 783
686 : 1, 2, 7, 14, 49, 98, 343, 686
138 : 1, 2, 3, 6, 23, 46, 69, 138
439 : 1, 439
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,783,686,138,439, is 1.
Now, the common factors can be found like this.
439:439
783:3x 3x 3x 29
686:2x 7x 7x 7
138:2x 3x 23
439:439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 439 = 2634
Therefore, the value for common factors is 2634.
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 = 14285452604724/(1x2634)
LCM = 14285452604724/2634
LCM = 5423482386
Thus, we can understand that the LCM of 439,783,686,138,439 is 5423482386.
