Given numbers are 824,280,891,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 824,280,891,984 is 1053554040.
Find LCM of 824,280,891,984 with Prime Factorization
| 2 | 824, 280, 891, 984 |
| 2 | 412, 140, 891, 492 |
| 2 | 206, 70, 891, 246 |
| 3 | 103, 35, 891, 123 |
| 103, 35, 297, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 103 x 35 x 297 x 41 = 1053554040
Therefore, the lowest common multiple of 824,280,891,984 is 1053554040.
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.
824 x 280 x 891 x 984 = 202282375680
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,280,891,984, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
280:2x 2x 2x 5x 7
891:3x 3x 3x 3x 11
984:2x 2x 2x 3x 41
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 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 202282375680/(1x192)
LCM = 202282375680/192
LCM = 1053554040
Thus, we can understand that the LCM of 824,280,891,984 is 1053554040.
