Given numbers are 284,857,418,408,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 284,857,418,408,938 is 2433427785096.
Find LCM of 284,857,418,408,938 with Prime Factorization
| 2 | 284, 857, 418, 408, 938 |
| 2 | 142, 857, 209, 204, 469 |
| 71, 857, 209, 102, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 857 x 209 x 102 x 469 = 2433427785096
Therefore, the lowest common multiple of 284,857,418,408,938 is 2433427785096.
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.
284 x 857 x 418 x 408 x 938 = 38934844561536
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.
284 : 1, 2, 4, 71, 142, 284
857 : 1, 857
418 : 1, 2, 11, 19, 22, 38, 209, 418
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 284,857,418,408,938, is 1.
Now, the common factors can be found like this.
284:2x 2x 71
857:857
418:2x 11x 19
408:2x 2x 2x 3x 17
938:2x 7x 67
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 2 = 16
Therefore, the value for common factors is 16.
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 = 38934844561536/(1x16)
LCM = 38934844561536/16
LCM = 2433427785096
Thus, we can understand that the LCM of 284,857,418,408,938 is 2433427785096.
