Given numbers are 972,638,862,732,249
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,638,862,732,249 is 676615816404.
Find LCM of 972,638,862,732,249 with Prime Factorization
| 2 | 972, 638, 862, 732, 249 |
| 2 | 486, 319, 431, 366, 249 |
| 3 | 243, 319, 431, 183, 249 |
| 81, 319, 431, 61, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 81 x 319 x 431 x 61 x 83 = 676615816404
Therefore, the lowest common multiple of 972,638,862,732,249 is 676615816404.
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.
972 x 638 x 862 x 732 x 249 = 97432677562176
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
638 : 1, 2, 11, 22, 29, 58, 319, 638
862 : 1, 2, 431, 862
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
249 : 1, 3, 83, 249
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,638,862,732,249, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
638:2x 11x 29
862:2x 431
732:2x 2x 3x 61
249:3x 83
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 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 97432677562176/(1x144)
LCM = 97432677562176/144
LCM = 676615816404
Thus, we can understand that the LCM of 972,638,862,732,249 is 676615816404.
