Given numbers are 811,656,205,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,656,205,521 is 1385901680.
Find LCM of 811,656,205,521 with Prime Factorization
41 | 811, 656, 205, 521 |
811, 16, 5, 521 |
Multiply the prime numbers at the bottom and the left side.
41 x 811 x 16 x 5 x 521 = 1385901680
Therefore, the lowest common multiple of 811,656,205,521 is 1385901680.
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.
811 x 656 x 205 x 521 = 56821968880
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.
811 : 1, 811
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
205 : 1, 5, 41, 205
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,656,205,521, is 1.
Now, the common factors can be found like this.
811:811
656:2x 2x 2x 2x 41
205:5x 41
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
41 = 41
Therefore, the value for common factors is 41.
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 = 56821968880/(1x41)
LCM = 56821968880/41
LCM = 1385901680
Thus, we can understand that the LCM of 811,656,205,521 is 1385901680.
