Given numbers are 338,642,196,192
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,642,196,192 is 170124864.
Find LCM of 338,642,196,192 with Prime Factorization
| 2 | 338, 642, 196, 192 |
| 2 | 169, 321, 98, 96 |
| 3 | 169, 321, 49, 48 |
| 169, 107, 49, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 169 x 107 x 49 x 16 = 170124864
Therefore, the lowest common multiple of 338,642,196,192 is 170124864.
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.
338 x 642 x 196 x 192 = 8165993472
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.
338 : 1, 2, 13, 26, 169, 338
642 : 1, 2, 3, 6, 107, 214, 321, 642
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,642,196,192, is 2.
Now, the common factors can be found like this.
338:2x 13x 13
642:2x 3x 107
196:2x 2x 7x 7
192:2x 2x 2x 2x 2x 2x 3
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 8165993472/(2x24)
LCM = 8165993472/48
LCM = 170124864
Thus, we can understand that the LCM of 338,642,196,192 is 170124864.
