Given numbers are 825,281,621,121,977
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 825,281,621,121,977 is 515724617925.
Find LCM of 825,281,621,121,977 with Prime Factorization
| 3 | 825, 281, 621, 121, 977 |
| 11 | 275, 281, 207, 121, 977 |
| 25, 281, 207, 11, 977 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 25 x 281 x 207 x 11 x 977 = 515724617925
Therefore, the lowest common multiple of 825,281,621,121,977 is 515724617925.
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.
825 x 281 x 621 x 121 x 977 = 17018912391525
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
281 : 1, 281
621 : 1, 3, 9, 23, 27, 69, 207, 621
121 : 1, 11, 121
977 : 1, 977
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,281,621,121,977, is 1.
Now, the common factors can be found like this.
825:3x 5x 5x 11
281:281
621:3x 3x 3x 23
121:11x 11
977:977
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 17018912391525/(1x33)
LCM = 17018912391525/33
LCM = 515724617925
Thus, we can understand that the LCM of 825,281,621,121,977 is 515724617925.
