Given numbers are 190,561,722,574
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 190,561,722,574 is 581235270.
Find LCM of 190,561,722,574 with Prime Factorization
| 2 | 190, 561, 722, 574 |
| 19 | 95, 561, 361, 287 |
| 5, 561, 19, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 5 x 561 x 19 x 287 = 581235270
Therefore, the lowest common multiple of 190,561,722,574 is 581235270.
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.
190 x 561 x 722 x 574 = 44173880520
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.
190 : 1, 2, 5, 10, 19, 38, 95, 190
561 : 1, 3, 11, 17, 33, 51, 187, 561
722 : 1, 2, 19, 38, 361, 722
574 : 1, 2, 7, 14, 41, 82, 287, 574
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,561,722,574, is 1.
Now, the common factors can be found like this.
190:2x 5x 19
561:3x 11x 17
722:2x 19x 19
574:2x 7x 41
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 19 = 76
Therefore, the value for common factors is 76.
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 = 44173880520/(1x76)
LCM = 44173880520/76
LCM = 581235270
Thus, we can understand that the LCM of 190,561,722,574 is 581235270.
