Given numbers are 289,816,866,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,816,866,771 is 1543690032.
Find LCM of 289,816,866,771 with Prime Factorization
2 | 289, 816, 866, 771 |
3 | 289, 408, 433, 771 |
17 | 289, 136, 433, 257 |
17, 8, 433, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 17 x 8 x 433 x 257 = 1543690032
Therefore, the lowest common multiple of 289,816,866,771 is 1543690032.
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.
289 x 816 x 866 x 771 = 157456383264
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.
289 : 1, 17, 289
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
866 : 1, 2, 433, 866
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,816,866,771, is 1.
Now, the common factors can be found like this.
289:17x 17
816:2x 2x 2x 2x 3x 17
866:2x 433
771:3x 257
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 17 = 102
Therefore, the value for common factors is 102.
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 = 157456383264/(1x102)
LCM = 157456383264/102
LCM = 1543690032
Thus, we can understand that the LCM of 289,816,866,771 is 1543690032.
