Given numbers are 815,121,561,494,404
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,121,561,494,404 is 501870274620.
Find LCM of 815,121,561,494,404 with Prime Factorization
2 | 815, 121, 561, 494, 404 |
11 | 815, 121, 561, 247, 202 |
815, 11, 51, 247, 202 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 815 x 11 x 51 x 247 x 202 = 501870274620
Therefore, the lowest common multiple of 815,121,561,494,404 is 501870274620.
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.
815 x 121 x 561 x 494 x 404 = 11041146041640
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.
815 : 1, 5, 163, 815
121 : 1, 11, 121
561 : 1, 3, 11, 17, 33, 51, 187, 561
494 : 1, 2, 13, 19, 26, 38, 247, 494
404 : 1, 2, 4, 101, 202, 404
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,121,561,494,404, is 1.
Now, the common factors can be found like this.
815:5x 163
121:11x 11
561:3x 11x 17
494:2x 13x 19
404:2x 2x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 11041146041640/(1x22)
LCM = 11041146041640/22
LCM = 501870274620
Thus, we can understand that the LCM of 815,121,561,494,404 is 501870274620.
