Given numbers are 843,426,322,966,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,426,322,966,990 is 3179989890.
Find LCM of 843,426,322,966,990 with Prime Factorization
| 2 | 843, 426, 322, 966, 990 |
| 3 | 843, 213, 161, 483, 495 |
| 7 | 281, 71, 161, 161, 165 |
| 23 | 281, 71, 23, 23, 165 |
| 281, 71, 1, 1, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 281 x 71 x 1 x 1 x 165 = 3179989890
Therefore, the lowest common multiple of 843,426,322,966,990 is 3179989890.
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.
843 x 426 x 322 x 966 x 990 = 110587328414640
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.
843 : 1, 3, 281, 843
426 : 1, 2, 3, 6, 71, 142, 213, 426
322 : 1, 2, 7, 14, 23, 46, 161, 322
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,426,322,966,990, is 1.
Now, the common factors can be found like this.
843:3x 281
426:2x 3x 71
322:2x 7x 23
966:2x 3x 7x 23
990:2x 3x 3x 5x 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 2x 3x 3x 3x 7x 23 = 34776
Therefore, the value for common factors is 34776.
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 = 110587328414640/(1x34776)
LCM = 110587328414640/34776
LCM = 3179989890
Thus, we can understand that the LCM of 843,426,322,966,990 is 3179989890.
