Given numbers are 457,981,833,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,981,833,438 is 54523416906.
Find LCM of 457,981,833,438 with Prime Factorization
| 3 | 457, 981, 833, 438 |
| 457, 327, 833, 146 |
Multiply the prime numbers at the bottom and the left side.
3 x 457 x 327 x 833 x 146 = 54523416906
Therefore, the lowest common multiple of 457,981,833,438 is 54523416906.
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.
457 x 981 x 833 x 438 = 163570250718
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.
457 : 1, 457
981 : 1, 3, 9, 109, 327, 981
833 : 1, 7, 17, 49, 119, 833
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,981,833,438, is 1.
Now, the common factors can be found like this.
457:457
981:3x 3x 109
833:7x 7x 17
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 163570250718/(1x3)
LCM = 163570250718/3
LCM = 54523416906
Thus, we can understand that the LCM of 457,981,833,438 is 54523416906.
