Given numbers are 531,921,674,783
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,921,674,783 is 9558990846.
Find LCM of 531,921,674,783 with Prime Factorization
| 3 | 531, 921, 674, 783 |
| 3 | 177, 307, 674, 261 |
| 59, 307, 674, 87 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 59 x 307 x 674 x 87 = 9558990846
Therefore, the lowest common multiple of 531,921,674,783 is 9558990846.
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.
531 x 921 x 674 x 783 = 258092752842
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.
531 : 1, 3, 9, 59, 177, 531
921 : 1, 3, 307, 921
674 : 1, 2, 337, 674
783 : 1, 3, 9, 27, 29, 87, 261, 783
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,921,674,783, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
921:3x 307
674:2x 337
783:3x 3x 3x 29
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 3 = 27
Therefore, the value for common factors is 27.
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 = 258092752842/(1x27)
LCM = 258092752842/27
LCM = 9558990846
Thus, we can understand that the LCM of 531,921,674,783 is 9558990846.
