Find LCM of 638,558,982,264,986 with Prime Factorization
| 2 | 638, 558, 982, 264, 986 |
| 3 | 319, 279, 491, 132, 493 |
| 11 | 319, 93, 491, 44, 493 |
| 29 | 29, 93, 491, 4, 493 |
| 1, 93, 491, 4, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 1 x 93 x 491 x 4 x 17 = 5943130776
Therefore, the lowest common multiple of 638,558,982,264,986 is 5943130776.
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.
638 x 558 x 982 x 264 x 986 = 91001218442112
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
982 : 1, 2, 491, 982
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
986 : 1, 2, 17, 29, 34, 58, 493, 986
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,558,982,264,986, is 2.
Now, the common factors can be found like this.
638:2x 11x 29
558:2x 3x 3x 31
982:2x 491
264:2x 2x 2x 3x 11
986:2x 17x 29
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 3x 11x 29 = 7656
Therefore, the value for common factors is 7656.
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 = 91001218442112/(2x7656)
LCM = 91001218442112/15312
LCM = 5943130776
Thus, we can understand that the LCM of 638,558,982,264,986 is 5943130776.
