Given numbers are 128,196,505,759,469
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,196,505,759,469 is 161069758080.
Find LCM of 128,196,505,759,469 with Prime Factorization
| 2 | 128, 196, 505, 759, 469 |
| 2 | 64, 98, 505, 759, 469 |
| 7 | 32, 49, 505, 759, 469 |
| 32, 7, 505, 759, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 32 x 7 x 505 x 759 x 67 = 161069758080
Therefore, the lowest common multiple of 128,196,505,759,469 is 161069758080.
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.
128 x 196 x 505 x 759 x 469 = 4509953226240
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
505 : 1, 5, 101, 505
759 : 1, 3, 11, 23, 33, 69, 253, 759
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,196,505,759,469, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
196:2x 2x 7x 7
505:5x 101
759:3x 11x 23
469:7x 67
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 7 = 28
Therefore, the value for common factors is 28.
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 = 4509953226240/(1x28)
LCM = 4509953226240/28
LCM = 161069758080
Thus, we can understand that the LCM of 128,196,505,759,469 is 161069758080.
