The LCM of 257,360,920,885 is 125549640.
Find LCM of 257,360,920,885 with Prime Factorization
| 2 | 257, 360, 920, 885 |
| 2 | 257, 180, 460, 885 |
| 2 | 257, 90, 230, 885 |
| 3 | 257, 45, 115, 885 |
| 5 | 257, 15, 115, 295 |
| 257, 3, 23, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 257 x 3 x 23 x 59 = 125549640
Therefore, the lowest common multiple of 257,360,920,885 is 125549640.
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 360 x 920 x 885 = 75329784000
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
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
885 : 1, 3, 5, 15, 59, 177, 295, 885
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,360,920,885, is 1.
Now, the common factors can be found like this.
257:257
360:2x 2x 2x 3x 3x 5
920:2x 2x 2x 5x 23
885:3x 5x 59
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 2x 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 75329784000/(1x600)
LCM = 75329784000/600
LCM = 125549640
Thus, we can understand that the LCM of 257,360,920,885 is 125549640.
