Given numbers are 501,789,821,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 501,789,821,165 is 5949758265.
Find LCM of 501,789,821,165 with Prime Factorization
| 3 | 501, 789, 821, 165 |
| 167, 263, 821, 55 |
Multiply the prime numbers at the bottom and the left side.
3 x 167 x 263 x 821 x 55 = 5949758265
Therefore, the lowest common multiple of 501,789,821,165 is 5949758265.
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.
501 x 789 x 821 x 165 = 53547824385
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.
501 : 1, 3, 167, 501
789 : 1, 3, 263, 789
821 : 1, 821
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,789,821,165, is 1.
Now, the common factors can be found like this.
501:3x 167
789:3x 263
821:821
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 53547824385/(1x9)
LCM = 53547824385/9
LCM = 5949758265
Thus, we can understand that the LCM of 501,789,821,165 is 5949758265.
