Given numbers are 684,753,792,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,753,792,422 is 796957128.
Find LCM of 684,753,792,422 with Prime Factorization
| 2 | 684, 753, 792, 422 |
| 2 | 342, 753, 396, 211 |
| 3 | 171, 753, 198, 211 |
| 3 | 57, 251, 66, 211 |
| 19, 251, 22, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 251 x 22 x 211 = 796957128
Therefore, the lowest common multiple of 684,753,792,422 is 796957128.
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.
684 x 753 x 792 x 422 = 172142739648
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
753 : 1, 3, 251, 753
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
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,753,792,422, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
753:3x 251
792:2x 2x 2x 3x 3x 11
422:2x 211
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 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 172142739648/(1x216)
LCM = 172142739648/216
LCM = 796957128
Thus, we can understand that the LCM of 684,753,792,422 is 796957128.
