Given numbers are 990,898,428,115,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,898,428,115,917 is 2006284327740.
Find LCM of 990,898,428,115,917 with Prime Factorization
2 | 990, 898, 428, 115, 917 |
5 | 495, 449, 214, 115, 917 |
99, 449, 214, 23, 917 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 99 x 449 x 214 x 23 x 917 = 2006284327740
Therefore, the lowest common multiple of 990,898,428,115,917 is 2006284327740.
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.
990 x 898 x 428 x 115 x 917 = 40125686554800
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
898 : 1, 2, 449, 898
428 : 1, 2, 4, 107, 214, 428
115 : 1, 5, 23, 115
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,898,428,115,917, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
898:2x 449
428:2x 2x 107
115:5x 23
917:7x 131
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 5 = 20
Therefore, the value for common factors is 20.
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 = 40125686554800/(1x20)
LCM = 40125686554800/20
LCM = 2006284327740
Thus, we can understand that the LCM of 990,898,428,115,917 is 2006284327740.
