Given numbers are 816,640,196,601
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,640,196,601 is 961215360.
Find LCM of 816,640,196,601 with Prime Factorization
| 2 | 816, 640, 196, 601 |
| 2 | 408, 320, 98, 601 |
| 2 | 204, 160, 49, 601 |
| 2 | 102, 80, 49, 601 |
| 51, 40, 49, 601 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 51 x 40 x 49 x 601 = 961215360
Therefore, the lowest common multiple of 816,640,196,601 is 961215360.
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.
816 x 640 x 196 x 601 = 61517783040
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
601 : 1, 601
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,640,196,601, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
640:2x 2x 2x 2x 2x 2x 2x 5
196:2x 2x 7x 7
601:601
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 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 61517783040/(1x64)
LCM = 61517783040/64
LCM = 961215360
Thus, we can understand that the LCM of 816,640,196,601 is 961215360.
