Given numbers are 829,756,622,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 829,756,622,431 is 84006711684.
Find LCM of 829,756,622,431 with Prime Factorization
| 2 | 829, 756, 622, 431 |
| 829, 378, 311, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 829 x 378 x 311 x 431 = 84006711684
Therefore, the lowest common multiple of 829,756,622,431 is 84006711684.
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.
829 x 756 x 622 x 431 = 168013423368
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.
829 : 1, 829
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
622 : 1, 2, 311, 622
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,756,622,431, is 1.
Now, the common factors can be found like this.
829:829
756:2x 2x 3x 3x 3x 7
622:2x 311
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 168013423368/(1x2)
LCM = 168013423368/2
LCM = 84006711684
Thus, we can understand that the LCM of 829,756,622,431 is 84006711684.
