Given numbers are 315,507,693,181,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,507,693,181,687 is 24271912665.
Find LCM of 315,507,693,181,687 with Prime Factorization
| 3 | 315, 507, 693, 181, 687 |
| 3 | 105, 169, 231, 181, 229 |
| 7 | 35, 169, 77, 181, 229 |
| 5, 169, 11, 181, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 5 x 169 x 11 x 181 x 229 = 24271912665
Therefore, the lowest common multiple of 315,507,693,181,687 is 24271912665.
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.
315 x 507 x 693 x 181 x 687 = 13762174481055
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
507 : 1, 3, 13, 39, 169, 507
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
181 : 1, 181
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,507,693,181,687, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
507:3x 13x 13
693:3x 3x 7x 11
181:181
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 3x 3x 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 13762174481055/(1x567)
LCM = 13762174481055/567
LCM = 24271912665
Thus, we can understand that the LCM of 315,507,693,181,687 is 24271912665.
