Given numbers are 9,988,855,722
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9,988,855,722 is 844740.
Find LCM of 9,988,855,722 with Prime Factorization
| 2 | 9, 988, 855, 722 |
| 3 | 9, 494, 855, 361 |
| 3 | 3, 494, 285, 361 |
| 19 | 1, 494, 95, 361 |
| 1, 26, 5, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 1 x 26 x 5 x 19 = 844740
Therefore, the lowest common multiple of 9,988,855,722 is 844740.
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.
9 x 988 x 855 x 722 = 5489120520
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.
9 : 1, 3, 9
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
722 : 1, 2, 19, 38, 361, 722
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9,988,855,722, is 1.
Now, the common factors can be found like this.
9:3x 3
988:2x 2x 13x 19
855:3x 3x 5x 19
722:2x 19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 19x 19 = 6498
Therefore, the value for common factors is 6498.
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 = 5489120520/(1x6498)
LCM = 5489120520/6498
LCM = 844740
Thus, we can understand that the LCM of 9,988,855,722 is 844740.
