The LCM of 808,161,368,728 is 3382288.
Find LCM of 808,161,368,728 with Prime Factorization
| 2 | 808, 161, 368, 728 |
| 2 | 404, 161, 184, 364 |
| 2 | 202, 161, 92, 182 |
| 7 | 101, 161, 46, 91 |
| 23 | 101, 23, 46, 13 |
| 101, 1, 2, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 23 x 101 x 1 x 2 x 13 = 3382288
Therefore, the lowest common multiple of 808,161,368,728 is 3382288.
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.
808 x 161 x 368 x 728 = 34851095552
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
161 : 1, 7, 23, 161
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,161,368,728, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
161:7x 23
368:2x 2x 2x 2x 23
728:2x 2x 2x 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 2x 2x 2x 2x 2x 7x 23 = 10304
Therefore, the value for common factors is 10304.
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 = 34851095552/(1x10304)
LCM = 34851095552/10304
LCM = 3382288
Thus, we can understand that the LCM of 808,161,368,728 is 3382288.
