Given numbers are 205,616,785,469
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 205,616,785,469 is 1328339320.
Find LCM of 205,616,785,469 with Prime Factorization
| 5 | 205, 616, 785, 469 |
| 7 | 41, 616, 157, 469 |
| 41, 88, 157, 67 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 41 x 88 x 157 x 67 = 1328339320
Therefore, the lowest common multiple of 205,616,785,469 is 1328339320.
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.
205 x 616 x 785 x 469 = 46491876200
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.
205 : 1, 5, 41, 205
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
785 : 1, 5, 157, 785
469 : 1, 7, 67, 469
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,616,785,469, is 1.
Now, the common factors can be found like this.
205:5x 41
616:2x 2x 2x 7x 11
785:5x 157
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.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 46491876200/(1x35)
LCM = 46491876200/35
LCM = 1328339320
Thus, we can understand that the LCM of 205,616,785,469 is 1328339320.
