Given numbers are 579,731,287,258
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,731,287,258 is 242944926.
Find LCM of 579,731,287,258 with Prime Factorization
| 3 | 579, 731, 287, 258 |
| 43 | 193, 731, 287, 86 |
| 193, 17, 287, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 193 x 17 x 287 x 2 = 242944926
Therefore, the lowest common multiple of 579,731,287,258 is 242944926.
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.
579 x 731 x 287 x 258 = 31339895454
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.
579 : 1, 3, 193, 579
731 : 1, 17, 43, 731
287 : 1, 7, 41, 287
258 : 1, 2, 3, 6, 43, 86, 129, 258
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,731,287,258, is 1.
Now, the common factors can be found like this.
579:3x 193
731:17x 43
287:7x 41
258:2x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 31339895454/(1x129)
LCM = 31339895454/129
LCM = 242944926
Thus, we can understand that the LCM of 579,731,287,258 is 242944926.
