Given numbers are 803,105,400,225,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,105,400,225,831 is 5605261200.
Find LCM of 803,105,400,225,831 with Prime Factorization
| 3 | 803, 105, 400, 225, 831 |
| 5 | 803, 35, 400, 75, 277 |
| 5 | 803, 7, 80, 15, 277 |
| 803, 7, 16, 3, 277 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 803 x 7 x 16 x 3 x 277 = 5605261200
Therefore, the lowest common multiple of 803,105,400,225,831 is 5605261200.
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.
803 x 105 x 400 x 225 x 831 = 6305918850000
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.
803 : 1, 11, 73, 803
105 : 1, 3, 5, 7, 15, 21, 35, 105
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,105,400,225,831, is 1.
Now, the common factors can be found like this.
803:11x 73
105:3x 5x 7
400:2x 2x 2x 2x 5x 5
225:3x 3x 5x 5
831:3x 277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 5 = 1125
Therefore, the value for common factors is 1125.
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 = 6305918850000/(1x1125)
LCM = 6305918850000/1125
LCM = 5605261200
Thus, we can understand that the LCM of 803,105,400,225,831 is 5605261200.
