Given numbers are 317,468,390,866
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 317,468,390,866 is 321190740.
Find LCM of 317,468,390,866 with Prime Factorization
| 2 | 317, 468, 390, 866 |
| 3 | 317, 234, 195, 433 |
| 13 | 317, 78, 65, 433 |
| 317, 6, 5, 433 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 317 x 6 x 5 x 433 = 321190740
Therefore, the lowest common multiple of 317,468,390,866 is 321190740.
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.
317 x 468 x 390 x 866 = 50105755440
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.
317 : 1, 317
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
866 : 1, 2, 433, 866
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,468,390,866, is 1.
Now, the common factors can be found like this.
317:317
468:2x 2x 3x 3x 13
390:2x 3x 5x 13
866:2x 433
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 13 = 156
Therefore, the value for common factors is 156.
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 = 50105755440/(1x156)
LCM = 50105755440/156
LCM = 321190740
Thus, we can understand that the LCM of 317,468,390,866 is 321190740.
