Given numbers are 531,885,215,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,885,215,791 is 90304515.
Find LCM of 531,885,215,791 with Prime Factorization
3 | 531, 885, 215, 791 |
5 | 177, 295, 215, 791 |
59 | 177, 59, 43, 791 |
3, 1, 43, 791 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 59 x 3 x 1 x 43 x 791 = 90304515
Therefore, the lowest common multiple of 531,885,215,791 is 90304515.
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 885 x 215 x 791 = 79919495775
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
885 : 1, 3, 5, 15, 59, 177, 295, 885
215 : 1, 5, 43, 215
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,885,215,791, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
885:3x 5x 59
215:5x 43
791:7x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 59 = 885
Therefore, the value for common factors is 885.
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 = 79919495775/(1x885)
LCM = 79919495775/885
LCM = 90304515
Thus, we can understand that the LCM of 531,885,215,791 is 90304515.
