Given numbers are 384,489,782,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 384,489,782,966 is 171314304.
Find LCM of 384,489,782,966 with Prime Factorization
| 2 | 384, 489, 782, 966 |
| 3 | 192, 489, 391, 483 |
| 23 | 64, 163, 391, 161 |
| 64, 163, 17, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 64 x 163 x 17 x 7 = 171314304
Therefore, the lowest common multiple of 384,489,782,966 is 171314304.
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.
384 x 489 x 782 x 966 = 141848243712
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.
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
489 : 1, 3, 163, 489
782 : 1, 2, 17, 23, 34, 46, 391, 782
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 384,489,782,966, is 1.
Now, the common factors can be found like this.
384:2x 2x 2x 2x 2x 2x 2x 3
489:3x 163
782:2x 17x 23
966:2x 3x 7x 23
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 3x 3x 23 = 828
Therefore, the value for common factors is 828.
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 = 141848243712/(1x828)
LCM = 141848243712/828
LCM = 171314304
Thus, we can understand that the LCM of 384,489,782,966 is 171314304.
