Given numbers are 166,774,620,782,864
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 166,774,620,782,864 is 186882547680.
Find LCM of 166,774,620,782,864 with Prime Factorization
| 2 | 166, 774, 620, 782, 864 |
| 2 | 83, 387, 310, 391, 432 |
| 3 | 83, 387, 155, 391, 216 |
| 3 | 83, 129, 155, 391, 72 |
| 83, 43, 155, 391, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 83 x 43 x 155 x 391 x 24 = 186882547680
Therefore, the lowest common multiple of 166,774,620,782,864 is 186882547680.
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.
166 x 774 x 620 x 782 x 864 = 53822173731840
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.
166 : 1, 2, 83, 166
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
782 : 1, 2, 17, 23, 34, 46, 391, 782
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 166,774,620,782,864, is 2.
Now, the common factors can be found like this.
166:2x 83
774:2x 3x 3x 43
620:2x 2x 5x 31
782:2x 17x 23
864:2x 2x 2x 2x 2x 3x 3x 3
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 53822173731840/(2x144)
LCM = 53822173731840/288
LCM = 186882547680
Thus, we can understand that the LCM of 166,774,620,782,864 is 186882547680.
