Given numbers are 687,387,387,367,999
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,387,387,367,999 is 3610235151.
Find LCM of 687,387,387,367,999 with Prime Factorization
| 3 | 687, 387, 387, 367, 999 |
| 3 | 229, 129, 129, 367, 333 |
| 43 | 229, 43, 43, 367, 111 |
| 229, 1, 1, 367, 111 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 43 x 229 x 1 x 1 x 367 x 111 = 3610235151
Therefore, the lowest common multiple of 687,387,387,367,999 is 3610235151.
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.
687 x 387 x 387 x 367 x 999 = 37723347092799
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.
687 : 1, 3, 229, 687
387 : 1, 3, 9, 43, 129, 387
387 : 1, 3, 9, 43, 129, 387
367 : 1, 367
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,387,387,367,999, is 1.
Now, the common factors can be found like this.
687:3x 229
387:3x 3x 43
387:3x 3x 43
367:367
999:3x 3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 43 = 10449
Therefore, the value for common factors is 10449.
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 = 37723347092799/(1x10449)
LCM = 37723347092799/10449
LCM = 3610235151
Thus, we can understand that the LCM of 687,387,387,367,999 is 3610235151.
