The LCM of 289,204,620,529,868 is 1990510620.
Find LCM of 289,204,620,529,868 with Prime Factorization
| 2 | 289, 204, 620, 529, 868 |
| 2 | 289, 102, 310, 529, 434 |
| 17 | 289, 51, 155, 529, 217 |
| 31 | 17, 3, 155, 529, 217 |
| 17, 3, 5, 529, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 31 x 17 x 3 x 5 x 529 x 7 = 1990510620
Therefore, the lowest common multiple of 289,204,620,529,868 is 1990510620.
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 204 x 620 x 529 x 868 = 16783985547840
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
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
529 : 1, 23, 529
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,204,620,529,868, is 1.
Now, the common factors can be found like this.
289:17x 17
204:2x 2x 3x 17
620:2x 2x 5x 31
529:23x 23
868:2x 2x 7x 31
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 17x 31 = 8432
Therefore, the value for common factors is 8432.
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 = 16783985547840/(1x8432)
LCM = 16783985547840/8432
LCM = 1990510620
Thus, we can understand that the LCM of 289,204,620,529,868 is 1990510620.
