Given numbers are 558,129,815,473,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,129,815,473,621 is 14842328490.
Find LCM of 558,129,815,473,621 with Prime Factorization
| 3 | 558, 129, 815, 473, 621 |
| 3 | 186, 43, 815, 473, 207 |
| 43 | 62, 43, 815, 473, 69 |
| 62, 1, 815, 11, 69 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 43 x 62 x 1 x 815 x 11 x 69 = 14842328490
Therefore, the lowest common multiple of 558,129,815,473,621 is 14842328490.
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.
558 x 129 x 815 x 473 x 621 = 17231943376890
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
129 : 1, 3, 43, 129
815 : 1, 5, 163, 815
473 : 1, 11, 43, 473
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,129,815,473,621, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
129:3x 43
815:5x 163
473:11x 43
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 43 = 1161
Therefore, the value for common factors is 1161.
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 = 17231943376890/(1x1161)
LCM = 17231943376890/1161
LCM = 14842328490
Thus, we can understand that the LCM of 558,129,815,473,621 is 14842328490.
