The LCM of 869,792,364,231 is 5693688.
Find LCM of 869,792,364,231 with Prime Factorization
| 2 | 869, 792, 364, 231 |
| 2 | 869, 396, 182, 231 |
| 3 | 869, 198, 91, 231 |
| 7 | 869, 66, 91, 77 |
| 11 | 869, 66, 13, 11 |
| 79, 6, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 79 x 6 x 13 x 1 = 5693688
Therefore, the lowest common multiple of 869,792,364,231 is 5693688.
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.
869 x 792 x 364 x 231 = 57870644832
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.
869 : 1, 11, 79, 869
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
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,792,364,231, is 1.
Now, the common factors can be found like this.
869:11x 79
792:2x 2x 2x 3x 3x 11
364:2x 2x 7x 13
231:3x 7x 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 7x 11x 11 = 10164
Therefore, the value for common factors is 10164.
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 = 57870644832/(1x10164)
LCM = 57870644832/10164
LCM = 5693688
Thus, we can understand that the LCM of 869,792,364,231 is 5693688.
