Find LCM of 388,639,208,923,935 with Prime Factorization
| 2 | 388, 639, 208, 923, 935 |
| 2 | 194, 639, 104, 923, 935 |
| 13 | 97, 639, 52, 923, 935 |
| 71 | 97, 639, 4, 71, 935 |
| 97, 9, 4, 1, 935 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 71 x 97 x 9 x 4 x 1 x 935 = 12054453840
Therefore, the lowest common multiple of 388,639,208,923,935 is 12054453840.
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.
388 x 639 x 208 x 923 x 935 = 44505043577280
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.
388 : 1, 2, 4, 97, 194, 388
639 : 1, 3, 9, 71, 213, 639
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
923 : 1, 13, 71, 923
935 : 1, 5, 11, 17, 55, 85, 187, 935
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,639,208,923,935, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
639:3x 3x 71
208:2x 2x 2x 2x 13
923:13x 71
935:5x 11x 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 13x 71 = 3692
Therefore, the value for common factors is 3692.
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 = 44505043577280/(1x3692)
LCM = 44505043577280/3692
LCM = 12054453840
Thus, we can understand that the LCM of 388,639,208,923,935 is 12054453840.
