Find LCM of 257,576,891,902 with Prime Factorization
| 2 | 257, 576, 891, 902 |
| 3 | 257, 288, 891, 451 |
| 3 | 257, 96, 297, 451 |
| 11 | 257, 32, 99, 451 |
| 257, 32, 9, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 257 x 32 x 9 x 41 = 600861888
Therefore, the lowest common multiple of 257,576,891,902 is 600861888.
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 576 x 891 x 902 = 118970653824
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
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,576,891,902, is 1.
Now, the common factors can be found like this.
257:257
576:2x 2x 2x 2x 2x 2x 3x 3
891:3x 3x 3x 3x 11
902:2x 11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11 = 198
Therefore, the value for common factors is 198.
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 = 118970653824/(1x198)
LCM = 118970653824/198
LCM = 600861888
Thus, we can understand that the LCM of 257,576,891,902 is 600861888.
