Given numbers are 945,422,195,255
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 945,422,195,255 is 88132590.
Find LCM of 945,422,195,255 with Prime Factorization
| 3 | 945, 422, 195, 255 |
| 5 | 315, 422, 65, 85 |
| 63, 422, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 63 x 422 x 13 x 17 = 88132590
Therefore, the lowest common multiple of 945,422,195,255 is 88132590.
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.
945 x 422 x 195 x 255 = 19829832750
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
422 : 1, 2, 211, 422
195 : 1, 3, 5, 13, 15, 39, 65, 195
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,422,195,255, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
422:2x 211
195:3x 5x 13
255:3x 5x 17
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 5 = 225
Therefore, the value for common factors is 225.
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 = 19829832750/(1x225)
LCM = 19829832750/225
LCM = 88132590
Thus, we can understand that the LCM of 945,422,195,255 is 88132590.
