Given numbers are 271,756,679,642,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 271,756,679,642,343 is 104193992196.
Find LCM of 271,756,679,642,343 with Prime Factorization
| 2 | 271, 756, 679, 642, 343 |
| 3 | 271, 378, 679, 321, 343 |
| 7 | 271, 126, 679, 107, 343 |
| 271, 18, 97, 107, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 271 x 18 x 97 x 107 x 49 = 104193992196
Therefore, the lowest common multiple of 271,756,679,642,343 is 104193992196.
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.
271 x 756 x 679 x 642 x 343 = 30633033705624
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.
271 : 1, 271
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
679 : 1, 7, 97, 679
642 : 1, 2, 3, 6, 107, 214, 321, 642
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 271,756,679,642,343, is 1.
Now, the common factors can be found like this.
271:271
756:2x 2x 3x 3x 3x 7
679:7x 97
642:2x 3x 107
343:7x 7x 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 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 30633033705624/(1x294)
LCM = 30633033705624/294
LCM = 104193992196
Thus, we can understand that the LCM of 271,756,679,642,343 is 104193992196.
