Given numbers are 825,165,921,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 825,165,921,154 is 3545850.
Find LCM of 825,165,921,154 with Prime Factorization
| 3 | 825, 165, 921, 154 |
| 5 | 275, 55, 307, 154 |
| 11 | 11, 55, 307, 154 |
| 1, 5, 307, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 1 x 5 x 307 x 14 = 3545850
Therefore, the lowest common multiple of 825,165,921,154 is 3545850.
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.
825 x 165 x 921 x 154 = 19307153250
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.
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
165 : 1, 3, 5, 11, 15, 33, 55, 165
921 : 1, 3, 307, 921
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,165,921,154, is 1.
Now, the common factors can be found like this.
825:3x 5x 5x 11
165:3x 5x 11
921:3x 307
154:2x 7x 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 3x 5x 11x 11 = 5445
Therefore, the value for common factors is 5445.
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 = 19307153250/(1x5445)
LCM = 19307153250/5445
LCM = 3545850
Thus, we can understand that the LCM of 825,165,921,154 is 3545850.
