Given numbers are 635,987,565,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,987,565,687 is 16218280365.
Find LCM of 635,987,565,687 with Prime Factorization
| 3 | 635, 987, 565, 687 |
| 5 | 635, 329, 565, 229 |
| 127, 329, 113, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 127 x 329 x 113 x 229 = 16218280365
Therefore, the lowest common multiple of 635,987,565,687 is 16218280365.
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.
635 x 987 x 565 x 687 = 243274205475
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.
635 : 1, 5, 127, 635
987 : 1, 3, 7, 21, 47, 141, 329, 987
565 : 1, 5, 113, 565
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,987,565,687, is 1.
Now, the common factors can be found like this.
635:5x 127
987:3x 7x 47
565:5x 113
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 243274205475/(1x15)
LCM = 243274205475/15
LCM = 16218280365
Thus, we can understand that the LCM of 635,987,565,687 is 16218280365.
