Given numbers are 192,338,169,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 192,338,169,663 is 551616.
Find LCM of 192,338,169,663 with Prime Factorization
| 2 | 192, 338, 169, 663 |
| 3 | 96, 169, 169, 663 |
| 13 | 32, 169, 169, 221 |
| 13 | 32, 13, 13, 17 |
| 32, 1, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 13 x 32 x 1 x 1 x 17 = 551616
Therefore, the lowest common multiple of 192,338,169,663 is 551616.
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.
192 x 338 x 169 x 663 = 7271402112
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
338 : 1, 2, 13, 26, 169, 338
169 : 1, 13, 169
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,338,169,663, is 1.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
338:2x 13x 13
169:13x 13
663:3x 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 3x 13x 13x 13 = 13182
Therefore, the value for common factors is 13182.
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 = 7271402112/(1x13182)
LCM = 7271402112/13182
LCM = 551616
Thus, we can understand that the LCM of 192,338,169,663 is 551616.
