Given numbers are 439,581,308,938,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 439,581,308,938,638 is 21805504028.
Find LCM of 439,581,308,938,638 with Prime Factorization
| 2 | 439, 581, 308, 938, 638 |
| 7 | 439, 581, 154, 469, 319 |
| 11 | 439, 83, 22, 67, 319 |
| 439, 83, 2, 67, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 439 x 83 x 2 x 67 x 29 = 21805504028
Therefore, the lowest common multiple of 439,581,308,938,638 is 21805504028.
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 581 x 308 x 938 x 638 = 47012666684368
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
581 : 1, 7, 83, 581
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
938 : 1, 2, 7, 14, 67, 134, 469, 938
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,581,308,938,638, is 1.
Now, the common factors can be found like this.
439:439
581:7x 83
308:2x 2x 7x 11
938:2x 7x 67
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7x 7x 11 = 2156
Therefore, the value for common factors is 2156.
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 = 47012666684368/(1x2156)
LCM = 47012666684368/2156
LCM = 21805504028
Thus, we can understand that the LCM of 439,581,308,938,638 is 21805504028.
