Given numbers are 808,156,792,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,156,792,342 is 19758024.
Find LCM of 808,156,792,342 with Prime Factorization
| 2 | 808, 156, 792, 342 |
| 2 | 404, 78, 396, 171 |
| 2 | 202, 39, 198, 171 |
| 3 | 101, 39, 99, 171 |
| 3 | 101, 13, 33, 57 |
| 101, 13, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 101 x 13 x 11 x 19 = 19758024
Therefore, the lowest common multiple of 808,156,792,342 is 19758024.
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 156 x 792 x 342 = 34141865472
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
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,156,792,342, is 2.
Now, the common factors can be found like this.
808:2x 2x 2x 101
156:2x 2x 3x 13
792:2x 2x 2x 3x 3x 11
342:2x 3x 3x 19
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 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 34141865472/(2x864)
LCM = 34141865472/1728
LCM = 19758024
Thus, we can understand that the LCM of 808,156,792,342 is 19758024.
