Given numbers are 809,197,821,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 809,197,821,788 is 523380932.
Find LCM of 809,197,821,788 with Prime Factorization
197 | 809, 197, 821, 788 |
809, 1, 821, 4 |
Multiply the prime numbers at the bottom and the left side.
197 x 809 x 1 x 821 x 4 = 523380932
Therefore, the lowest common multiple of 809,197,821,788 is 523380932.
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.
809 x 197 x 821 x 788 = 103106043604
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.
809 : 1, 809
197 : 1, 197
821 : 1, 821
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,197,821,788, is 1.
Now, the common factors can be found like this.
809:809
197:197
821:821
788:2x 2x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
197 = 197
Therefore, the value for common factors is 197.
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 = 103106043604/(1x197)
LCM = 103106043604/197
LCM = 523380932
Thus, we can understand that the LCM of 809,197,821,788 is 523380932.
