Given numbers are 280,821,574,295,204
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,821,574,295,204 is 28360065720.
Find LCM of 280,821,574,295,204 with Prime Factorization
| 2 | 280, 821, 574, 295, 204 |
| 2 | 140, 821, 287, 295, 102 |
| 5 | 70, 821, 287, 295, 51 |
| 7 | 14, 821, 287, 59, 51 |
| 2, 821, 41, 59, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 2 x 821 x 41 x 59 x 51 = 28360065720
Therefore, the lowest common multiple of 280,821,574,295,204 is 28360065720.
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.
280 x 821 x 574 x 295 x 204 = 7940818401600
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
821 : 1, 821
574 : 1, 2, 7, 14, 41, 82, 287, 574
295 : 1, 5, 59, 295
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,821,574,295,204, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
821:821
574:2x 7x 41
295:5x 59
204:2x 2x 3x 17
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 7940818401600/(1x280)
LCM = 7940818401600/280
LCM = 28360065720
Thus, we can understand that the LCM of 280,821,574,295,204 is 28360065720.
