Given numbers are 9,390,988,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9,390,988,828 is 1022580.
Find LCM of 9,390,988,828 with Prime Factorization
| 2 | 9, 390, 988, 828 |
| 2 | 9, 195, 494, 414 |
| 3 | 9, 195, 247, 207 |
| 3 | 3, 65, 247, 69 |
| 13 | 1, 65, 247, 23 |
| 1, 5, 19, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 1 x 5 x 19 x 23 = 1022580
Therefore, the lowest common multiple of 9,390,988,828 is 1022580.
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 390 x 988 x 828 = 2871404640
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
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9,390,988,828, is 1.
Now, the common factors can be found like this.
9:3x 3
390:2x 3x 5x 13
988:2x 2x 13x 19
828:2x 2x 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.
2x 2x 2x 3x 3x 3x 13 = 2808
Therefore, the value for common factors is 2808.
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 = 2871404640/(1x2808)
LCM = 2871404640/2808
LCM = 1022580
Thus, we can understand that the LCM of 9,390,988,828 is 1022580.
