Given numbers are 808,682,921,157
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,682,921,157 is 39840522216.
Find LCM of 808,682,921,157 with Prime Factorization
| 2 | 808, 682, 921, 157 |
| 404, 341, 921, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 404 x 341 x 921 x 157 = 39840522216
Therefore, the lowest common multiple of 808,682,921,157 is 39840522216.
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.
808 x 682 x 921 x 157 = 79681044432
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
682 : 1, 2, 11, 22, 31, 62, 341, 682
921 : 1, 3, 307, 921
157 : 1, 157
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,682,921,157, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
682:2x 11x 31
921:3x 307
157:157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 79681044432/(1x2)
LCM = 79681044432/2
LCM = 39840522216
Thus, we can understand that the LCM of 808,682,921,157 is 39840522216.
