Given numbers are 257,568,253,686,273
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,568,253,686,273 is 494038400856.
Find LCM of 257,568,253,686,273 with Prime Factorization
| 2 | 257, 568, 253, 686, 273 |
| 7 | 257, 284, 253, 343, 273 |
| 257, 284, 253, 49, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 257 x 284 x 253 x 49 x 39 = 494038400856
Therefore, the lowest common multiple of 257,568,253,686,273 is 494038400856.
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.
257 x 568 x 253 x 686 x 273 = 6916537611984
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.
257 : 1, 257
568 : 1, 2, 4, 8, 71, 142, 284, 568
253 : 1, 11, 23, 253
686 : 1, 2, 7, 14, 49, 98, 343, 686
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,568,253,686,273, is 1.
Now, the common factors can be found like this.
257:257
568:2x 2x 2x 71
253:11x 23
686:2x 7x 7x 7
273:3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 6916537611984/(1x14)
LCM = 6916537611984/14
LCM = 494038400856
Thus, we can understand that the LCM of 257,568,253,686,273 is 494038400856.
