Given numbers are 820,901,816,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,901,816,180 is 26597520.
Find LCM of 820,901,816,180 with Prime Factorization
| 2 | 820, 901, 816, 180 |
| 2 | 410, 901, 408, 90 |
| 3 | 205, 901, 204, 45 |
| 5 | 205, 901, 68, 15 |
| 17 | 41, 901, 68, 3 |
| 41, 53, 4, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 41 x 53 x 4 x 3 = 26597520
Therefore, the lowest common multiple of 820,901,816,180 is 26597520.
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.
820 x 901 x 816 x 180 = 108517881600
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
901 : 1, 17, 53, 901
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,901,816,180, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
901:17x 53
816:2x 2x 2x 2x 3x 17
180:2x 2x 3x 3x 5
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 3x 5x 17 = 4080
Therefore, the value for common factors is 4080.
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 = 108517881600/(1x4080)
LCM = 108517881600/4080
LCM = 26597520
Thus, we can understand that the LCM of 820,901,816,180 is 26597520.
