Given numbers are 343,538,516,839,388
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,538,516,839,388 is 3874626074676.
Find LCM of 343,538,516,839,388 with Prime Factorization
| 2 | 343, 538, 516, 839, 388 |
| 2 | 343, 269, 258, 839, 194 |
| 343, 269, 129, 839, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 343 x 269 x 129 x 839 x 97 = 3874626074676
Therefore, the lowest common multiple of 343,538,516,839,388 is 3874626074676.
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.
343 x 538 x 516 x 839 x 388 = 30997008597408
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.
343 : 1, 7, 49, 343
538 : 1, 2, 269, 538
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
839 : 1, 839
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,538,516,839,388, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
538:2x 269
516:2x 2x 3x 43
839:839
388:2x 2x 97
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 2 = 8
Therefore, the value for common factors is 8.
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 = 30997008597408/(1x8)
LCM = 30997008597408/8
LCM = 3874626074676
Thus, we can understand that the LCM of 343,538,516,839,388 is 3874626074676.
