Given numbers are 203,644,541,845,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 203,644,541,845,621 is 230516280540.
Find LCM of 203,644,541,845,621 with Prime Factorization
| 7 | 203, 644, 541, 845, 621 |
| 23 | 29, 92, 541, 845, 621 |
| 29, 4, 541, 845, 27 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 29 x 4 x 541 x 845 x 27 = 230516280540
Therefore, the lowest common multiple of 203,644,541,845,621 is 230516280540.
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.
203 x 644 x 541 x 845 x 621 = 37113121166940
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.
203 : 1, 7, 29, 203
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
541 : 1, 541
845 : 1, 5, 13, 65, 169, 845
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 203,644,541,845,621, is 1.
Now, the common factors can be found like this.
203:7x 29
644:2x 2x 7x 23
541:541
845:5x 13x 13
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.
7x 23 = 161
Therefore, the value for common factors is 161.
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 = 37113121166940/(1x161)
LCM = 37113121166940/161
LCM = 230516280540
Thus, we can understand that the LCM of 203,644,541,845,621 is 230516280540.
