Given numbers are 547,920,874,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 547,920,874,621 is 258162120.
Find LCM of 547,920,874,621 with Prime Factorization
| 2 | 547, 920, 874, 621 |
| 23 | 547, 460, 437, 621 |
| 547, 20, 19, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 547 x 20 x 19 x 27 = 258162120
Therefore, the lowest common multiple of 547,920,874,621 is 258162120.
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.
547 x 920 x 874 x 621 = 273135522960
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.
547 : 1, 547
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
874 : 1, 2, 19, 23, 38, 46, 437, 874
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 547,920,874,621, is 1.
Now, the common factors can be found like this.
547:547
920:2x 2x 2x 5x 23
874:2x 19x 23
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.
2x 23x 23 = 1058
Therefore, the value for common factors is 1058.
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 = 273135522960/(1x1058)
LCM = 273135522960/1058
LCM = 258162120
Thus, we can understand that the LCM of 547,920,874,621 is 258162120.
