Find LCM of 261,503,945,399,125 with Prime Factorization
| 3 | 261, 503, 945, 399, 125 |
| 3 | 87, 503, 315, 133, 125 |
| 5 | 29, 503, 105, 133, 125 |
| 7 | 29, 503, 21, 133, 25 |
| 29, 503, 3, 19, 25 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 29 x 503 x 3 x 19 x 25 = 6547739625
Therefore, the lowest common multiple of 261,503,945,399,125 is 6547739625.
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.
261 x 503 x 945 x 399 x 125 = 6187613945625
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.
261 : 1, 3, 9, 29, 87, 261
503 : 1, 503
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
399 : 1, 3, 7, 19, 21, 57, 133, 399
125 : 1, 5, 25, 125
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,503,945,399,125, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
503:503
945:3x 3x 3x 5x 7
399:3x 7x 19
125:5x 5x 5
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 3x 5x 7 = 945
Therefore, the value for common factors is 945.
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 = 6187613945625/(1x945)
LCM = 6187613945625/945
LCM = 6547739625
Thus, we can understand that the LCM of 261,503,945,399,125 is 6547739625.
