Given numbers are 838,403,469,268,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,403,469,268,942 is 149201369772.
Find LCM of 838,403,469,268,942 with Prime Factorization
| 2 | 838, 403, 469, 268, 942 |
| 67 | 419, 403, 469, 134, 471 |
| 419, 403, 7, 2, 471 |
Multiply the prime numbers at the bottom and the left side.
2 x 67 x 419 x 403 x 7 x 2 x 471 = 149201369772
Therefore, the lowest common multiple of 838,403,469,268,942 is 149201369772.
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.
838 x 403 x 469 x 268 x 942 = 39985967098896
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.
838 : 1, 2, 419, 838
403 : 1, 13, 31, 403
469 : 1, 7, 67, 469
268 : 1, 2, 4, 67, 134, 268
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,403,469,268,942, is 1.
Now, the common factors can be found like this.
838:2x 419
403:13x 31
469:7x 67
268:2x 2x 67
942:2x 3x 157
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 67 = 268
Therefore, the value for common factors is 268.
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 = 39985967098896/(1x268)
LCM = 39985967098896/268
LCM = 149201369772
Thus, we can understand that the LCM of 838,403,469,268,942 is 149201369772.
