Given numbers are 386,988,304,109
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 386,988,304,109 is 83138224.
Find LCM of 386,988,304,109 with Prime Factorization
| 2 | 386, 988, 304, 109 |
| 2 | 193, 494, 152, 109 |
| 19 | 193, 247, 76, 109 |
| 193, 13, 4, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 193 x 13 x 4 x 109 = 83138224
Therefore, the lowest common multiple of 386,988,304,109 is 83138224.
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.
386 x 988 x 304 x 109 = 12637010048
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.
386 : 1, 2, 193, 386
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
109 : 1, 109
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,988,304,109, is 1.
Now, the common factors can be found like this.
386:2x 193
988:2x 2x 13x 19
304:2x 2x 2x 2x 19
109:109
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 19 = 152
Therefore, the value for common factors is 152.
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 = 12637010048/(1x152)
LCM = 12637010048/152
LCM = 83138224
Thus, we can understand that the LCM of 386,988,304,109 is 83138224.
