Given numbers are 687,589,108,298,126
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,589,108,298,126 is 15193535364.
Find LCM of 687,589,108,298,126 with Prime Factorization
| 2 | 687, 589, 108, 298, 126 |
| 3 | 687, 589, 54, 149, 63 |
| 3 | 229, 589, 18, 149, 21 |
| 229, 589, 6, 149, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 229 x 589 x 6 x 149 x 7 = 15193535364
Therefore, the lowest common multiple of 687,589,108,298,126 is 15193535364.
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 589 x 108 x 298 x 126 = 1640901819312
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
589 : 1, 19, 31, 589
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
298 : 1, 2, 149, 298
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,589,108,298,126, is 1.
Now, the common factors can be found like this.
687:3x 229
589:19x 31
108:2x 2x 3x 3x 3
298:2x 149
126:2x 3x 3x 7
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 1640901819312/(1x108)
LCM = 1640901819312/108
LCM = 15193535364
Thus, we can understand that the LCM of 687,589,108,298,126 is 15193535364.
