Given numbers are 528,531,759,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 528,531,759,138 is 2149488.
Find LCM of 528,531,759,138 with Prime Factorization
| 2 | 528, 531, 759, 138 |
| 3 | 264, 531, 759, 69 |
| 11 | 88, 177, 253, 23 |
| 23 | 8, 177, 23, 23 |
| 8, 177, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 23 x 8 x 177 x 1 x 1 = 2149488
Therefore, the lowest common multiple of 528,531,759,138 is 2149488.
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.
528 x 531 x 759 x 138 = 29366305056
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.
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
531 : 1, 3, 9, 59, 177, 531
759 : 1, 3, 11, 23, 33, 69, 253, 759
138 : 1, 2, 3, 6, 23, 46, 69, 138
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 528,531,759,138, is 3.
Now, the common factors can be found like this.
528:2x 2x 2x 2x 3x 11
531:3x 3x 59
759:3x 11x 23
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 11x 23 = 4554
Therefore, the value for common factors is 4554.
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 = 29366305056/(3x4554)
LCM = 29366305056/13662
LCM = 2149488
Thus, we can understand that the LCM of 528,531,759,138 is 2149488.
