Given numbers are 831,746,706,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 831,746,706,798 is 29104905774.
Find LCM of 831,746,706,798 with Prime Factorization
| 2 | 831, 746, 706, 798 |
| 3 | 831, 373, 353, 399 |
| 277, 373, 353, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 277 x 373 x 353 x 133 = 29104905774
Therefore, the lowest common multiple of 831,746,706,798 is 29104905774.
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.
831 x 746 x 706 x 798 = 349258869288
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.
831 : 1, 3, 277, 831
746 : 1, 2, 373, 746
706 : 1, 2, 353, 706
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,746,706,798, is 1.
Now, the common factors can be found like this.
831:3x 277
746:2x 373
706:2x 353
798:2x 3x 7x 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 3 = 12
Therefore, the value for common factors is 12.
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 = 349258869288/(1x12)
LCM = 349258869288/12
LCM = 29104905774
Thus, we can understand that the LCM of 831,746,706,798 is 29104905774.
