Given numbers are 198,427,122,579
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 198,427,122,579 is 16317378.
Find LCM of 198,427,122,579 with Prime Factorization
| 2 | 198, 427, 122, 579 |
| 3 | 99, 427, 61, 579 |
| 61 | 33, 427, 61, 193 |
| 33, 7, 1, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 61 x 33 x 7 x 1 x 193 = 16317378
Therefore, the lowest common multiple of 198,427,122,579 is 16317378.
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.
198 x 427 x 122 x 579 = 5972160348
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.
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
427 : 1, 7, 61, 427
122 : 1, 2, 61, 122
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,427,122,579, is 1.
Now, the common factors can be found like this.
198:2x 3x 3x 11
427:7x 61
122:2x 61
579:3x 193
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 61 = 366
Therefore, the value for common factors is 366.
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 = 5972160348/(1x366)
LCM = 5972160348/366
LCM = 16317378
Thus, we can understand that the LCM of 198,427,122,579 is 16317378.
