Given numbers are 572,815,872,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 572,815,872,121 is 1117899640.
Find LCM of 572,815,872,121 with Prime Factorization
| 2 | 572, 815, 872, 121 |
| 2 | 286, 815, 436, 121 |
| 11 | 143, 815, 218, 121 |
| 13, 815, 218, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 815 x 218 x 11 = 1117899640
Therefore, the lowest common multiple of 572,815,872,121 is 1117899640.
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.
572 x 815 x 872 x 121 = 49187584160
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.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
815 : 1, 5, 163, 815
872 : 1, 2, 4, 8, 109, 218, 436, 872
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,815,872,121, is 1.
Now, the common factors can be found like this.
572:2x 2x 11x 13
815:5x 163
872:2x 2x 2x 109
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 49187584160/(1x44)
LCM = 49187584160/44
LCM = 1117899640
Thus, we can understand that the LCM of 572,815,872,121 is 1117899640.
