Given numbers are 439,669,671,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 439,669,671,309 is 20297866083.
Find LCM of 439,669,671,309 with Prime Factorization
| 3 | 439, 669, 671, 309 |
| 439, 223, 671, 103 |
Multiply the prime numbers at the bottom and the left side.
3 x 439 x 223 x 671 x 103 = 20297866083
Therefore, the lowest common multiple of 439,669,671,309 is 20297866083.
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 669 x 671 x 309 = 60893598249
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
669 : 1, 3, 223, 669
671 : 1, 11, 61, 671
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,669,671,309, is 1.
Now, the common factors can be found like this.
439:439
669:3x 223
671:11x 61
309:3x 103
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 = 60893598249/(1x3)
LCM = 60893598249/3
LCM = 20297866083
Thus, we can understand that the LCM of 439,669,671,309 is 20297866083.
