Given numbers are 923,221,257,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,221,257,731 is 173401241.
Find LCM of 923,221,257,731 with Prime Factorization
| 13 | 923, 221, 257, 731 |
| 17 | 71, 17, 257, 731 |
| 71, 1, 257, 43 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 71 x 1 x 257 x 43 = 173401241
Therefore, the lowest common multiple of 923,221,257,731 is 173401241.
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.
923 x 221 x 257 x 731 = 38321674261
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.
923 : 1, 13, 71, 923
221 : 1, 13, 17, 221
257 : 1, 257
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,221,257,731, is 1.
Now, the common factors can be found like this.
923:13x 71
221:13x 17
257:257
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 38321674261/(1x221)
LCM = 38321674261/221
LCM = 173401241
Thus, we can understand that the LCM of 923,221,257,731 is 173401241.
