Given numbers are 405,347,871,391,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,347,871,391,930 is 2967365888370.
Find LCM of 405,347,871,391,930 with Prime Factorization
| 3 | 405, 347, 871, 391, 930 |
| 5 | 135, 347, 871, 391, 310 |
| 27, 347, 871, 391, 62 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 27 x 347 x 871 x 391 x 62 = 2967365888370
Therefore, the lowest common multiple of 405,347,871,391,930 is 2967365888370.
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.
405 x 347 x 871 x 391 x 930 = 44510488325550
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
347 : 1, 347
871 : 1, 13, 67, 871
391 : 1, 17, 23, 391
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,347,871,391,930, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
347:347
871:13x 67
391:17x 23
930:2x 3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 44510488325550/(1x15)
LCM = 44510488325550/15
LCM = 2967365888370
Thus, we can understand that the LCM of 405,347,871,391,930 is 2967365888370.
