Given numbers are 538,654,638,988,130
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,654,638,988,130 is 138617373180.
Find LCM of 538,654,638,988,130 with Prime Factorization
| 2 | 538, 654, 638, 988, 130 |
| 13 | 269, 327, 319, 494, 65 |
| 269, 327, 319, 38, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 269 x 327 x 319 x 38 x 5 = 138617373180
Therefore, the lowest common multiple of 538,654,638,988,130 is 138617373180.
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.
538 x 654 x 638 x 988 x 130 = 28832413621440
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.
538 : 1, 2, 269, 538
654 : 1, 2, 3, 6, 109, 218, 327, 654
638 : 1, 2, 11, 22, 29, 58, 319, 638
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
130 : 1, 2, 5, 10, 13, 26, 65, 130
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,654,638,988,130, is 2.
Now, the common factors can be found like this.
538:2x 269
654:2x 3x 109
638:2x 11x 29
988:2x 2x 13x 19
130:2x 5x 13
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 13 = 104
Therefore, the value for common factors is 104.
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 = 28832413621440/(2x104)
LCM = 28832413621440/208
LCM = 138617373180
Thus, we can understand that the LCM of 538,654,638,988,130 is 138617373180.
