Given numbers are 190,904,665,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 190,904,665,442 is 132856360.
Find LCM of 190,904,665,442 with Prime Factorization
| 2 | 190, 904, 665, 442 |
| 5 | 95, 452, 665, 221 |
| 19 | 19, 452, 133, 221 |
| 1, 452, 7, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 1 x 452 x 7 x 221 = 132856360
Therefore, the lowest common multiple of 190,904,665,442 is 132856360.
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 904 x 665 x 442 = 50485416800
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
904 : 1, 2, 4, 8, 113, 226, 452, 904
665 : 1, 5, 7, 19, 35, 95, 133, 665
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,904,665,442, is 1.
Now, the common factors can be found like this.
190:2x 5x 19
904:2x 2x 2x 113
665:5x 7x 19
442:2x 13x 17
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 5x 19 = 380
Therefore, the value for common factors is 380.
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 = 50485416800/(1x380)
LCM = 50485416800/380
LCM = 132856360
Thus, we can understand that the LCM of 190,904,665,442 is 132856360.
