Given numbers are 993,561,832,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,561,832,798 is 20547823296.
Find LCM of 993,561,832,798 with Prime Factorization
| 2 | 993, 561, 832, 798 |
| 3 | 993, 561, 416, 399 |
| 331, 187, 416, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 331 x 187 x 416 x 133 = 20547823296
Therefore, the lowest common multiple of 993,561,832,798 is 20547823296.
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.
993 x 561 x 832 x 798 = 369860819328
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.
993 : 1, 3, 331, 993
561 : 1, 3, 11, 17, 33, 51, 187, 561
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
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 993,561,832,798, is 1.
Now, the common factors can be found like this.
993:3x 331
561:3x 11x 17
832:2x 2x 2x 2x 2x 2x 13
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 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 369860819328/(1x18)
LCM = 369860819328/18
LCM = 20547823296
Thus, we can understand that the LCM of 993,561,832,798 is 20547823296.
