Given numbers are 242,671,374,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 242,671,374,687 is 172405398.
Find LCM of 242,671,374,687 with Prime Factorization
| 2 | 242, 671, 374, 687 |
| 11 | 121, 671, 187, 687 |
| 11, 61, 17, 687 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 61 x 17 x 687 = 172405398
Therefore, the lowest common multiple of 242,671,374,687 is 172405398.
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.
242 x 671 x 374 x 687 = 41722106316
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.
242 : 1, 2, 11, 22, 121, 242
671 : 1, 11, 61, 671
374 : 1, 2, 11, 17, 22, 34, 187, 374
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,671,374,687, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
671:11x 61
374:2x 11x 17
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.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 41722106316/(1x242)
LCM = 41722106316/242
LCM = 172405398
Thus, we can understand that the LCM of 242,671,374,687 is 172405398.
