The LCM of 257,368,909,644,297 is 19858973904.
Find LCM of 257,368,909,644,297 with Prime Factorization
| 2 | 257, 368, 909, 644, 297 |
| 2 | 257, 184, 909, 322, 297 |
| 3 | 257, 92, 909, 161, 297 |
| 3 | 257, 92, 303, 161, 99 |
| 23 | 257, 92, 101, 161, 33 |
| 257, 4, 101, 7, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 257 x 4 x 101 x 7 x 33 = 19858973904
Therefore, the lowest common multiple of 257,368,909,644,297 is 19858973904.
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 368 x 909 x 644 x 297 = 16443230392512
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
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
909 : 1, 3, 9, 101, 303, 909
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
297 : 1, 3, 9, 11, 27, 33, 99, 297
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,368,909,644,297, is 1.
Now, the common factors can be found like this.
257:257
368:2x 2x 2x 2x 23
909:3x 3x 101
644:2x 2x 7x 23
297:3x 3x 3x 11
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 3x 3x 23 = 828
Therefore, the value for common factors is 828.
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 = 16443230392512/(1x828)
LCM = 16443230392512/828
LCM = 19858973904
Thus, we can understand that the LCM of 257,368,909,644,297 is 19858973904.
