Given numbers are 169,418,247,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,418,247,687 is 48531054.
Find LCM of 169,418,247,687 with Prime Factorization
| 13 | 169, 418, 247, 687 |
| 19 | 13, 418, 19, 687 |
| 13, 22, 1, 687 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 13 x 22 x 1 x 687 = 48531054
Therefore, the lowest common multiple of 169,418,247,687 is 48531054.
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.
169 x 418 x 247 x 687 = 11987170338
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.
169 : 1, 13, 169
418 : 1, 2, 11, 19, 22, 38, 209, 418
247 : 1, 13, 19, 247
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,418,247,687, is 1.
Now, the common factors can be found like this.
169:13x 13
418:2x 11x 19
247:13x 19
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.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 11987170338/(1x247)
LCM = 11987170338/247
LCM = 48531054
Thus, we can understand that the LCM of 169,418,247,687 is 48531054.
