Find LCM of 687,452,552,885,531 with Prime Factorization
| 2 | 687, 452, 552, 885, 531 |
| 2 | 687, 226, 276, 885, 531 |
| 3 | 687, 113, 138, 885, 531 |
| 59 | 229, 113, 46, 295, 177 |
| 229, 113, 46, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 59 x 229 x 113 x 46 x 5 x 3 = 12641432040
Therefore, the lowest common multiple of 687,452,552,885,531 is 12641432040.
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.
687 x 452 x 552 x 885 x 531 = 80551204958880
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.
687 : 1, 3, 229, 687
452 : 1, 2, 4, 113, 226, 452
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
885 : 1, 3, 5, 15, 59, 177, 295, 885
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,452,552,885,531, is 1.
Now, the common factors can be found like this.
687:3x 229
452:2x 2x 113
552:2x 2x 2x 3x 23
885:3x 5x 59
531:3x 3x 59
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 3x 3x 3x 59 = 6372
Therefore, the value for common factors is 6372.
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 = 80551204958880/(1x6372)
LCM = 80551204958880/6372
LCM = 12641432040
Thus, we can understand that the LCM of 687,452,552,885,531 is 12641432040.
