Given numbers are 816,255,349,497
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,255,349,497 is 707688240.
Find LCM of 816,255,349,497 with Prime Factorization
| 3 | 816, 255, 349, 497 |
| 17 | 272, 85, 349, 497 |
| 16, 5, 349, 497 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 16 x 5 x 349 x 497 = 707688240
Therefore, the lowest common multiple of 816,255,349,497 is 707688240.
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.
816 x 255 x 349 x 497 = 36092100240
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
255 : 1, 3, 5, 15, 17, 51, 85, 255
349 : 1, 349
497 : 1, 7, 71, 497
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,255,349,497, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
255:3x 5x 17
349:349
497:7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 36092100240/(1x51)
LCM = 36092100240/51
LCM = 707688240
Thus, we can understand that the LCM of 816,255,349,497 is 707688240.
