Given numbers are 989,271,105,559,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,271,105,559,728 is 2926767480.
Find LCM of 989,271,105,559,728 with Prime Factorization
| 7 | 989, 271, 105, 559, 728 |
| 13 | 989, 271, 15, 559, 104 |
| 43 | 989, 271, 15, 43, 8 |
| 23, 271, 15, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 43 x 23 x 271 x 15 x 1 x 8 = 2926767480
Therefore, the lowest common multiple of 989,271,105,559,728 is 2926767480.
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.
989 x 271 x 105 x 559 x 728 = 11452441149240
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.
989 : 1, 23, 43, 989
271 : 1, 271
105 : 1, 3, 5, 7, 15, 21, 35, 105
559 : 1, 13, 43, 559
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,271,105,559,728, is 1.
Now, the common factors can be found like this.
989:23x 43
271:271
105:3x 5x 7
559:13x 43
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13x 43 = 3913
Therefore, the value for common factors is 3913.
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 = 11452441149240/(1x3913)
LCM = 11452441149240/3913
LCM = 2926767480
Thus, we can understand that the LCM of 989,271,105,559,728 is 2926767480.
