Given numbers are 674,338,654,494,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 674,338,654,494,643 is 455049799854.
Find LCM of 674,338,654,494,643 with Prime Factorization
| 2 | 674, 338, 654, 494, 643 |
| 13 | 337, 169, 327, 247, 643 |
| 337, 13, 327, 19, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 337 x 13 x 327 x 19 x 643 = 455049799854
Therefore, the lowest common multiple of 674,338,654,494,643 is 455049799854.
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.
674 x 338 x 654 x 494 x 643 = 47325179184816
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.
674 : 1, 2, 337, 674
338 : 1, 2, 13, 26, 169, 338
654 : 1, 2, 3, 6, 109, 218, 327, 654
494 : 1, 2, 13, 19, 26, 38, 247, 494
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 674,338,654,494,643, is 1.
Now, the common factors can be found like this.
674:2x 337
338:2x 13x 13
654:2x 3x 109
494:2x 13x 19
643:643
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 47325179184816/(1x104)
LCM = 47325179184816/104
LCM = 455049799854
Thus, we can understand that the LCM of 674,338,654,494,643 is 455049799854.
