The LCM of 684,988,402,957 is 190048716.
Find LCM of 684,988,402,957 with Prime Factorization
| 2 | 684, 988, 402, 957 |
| 2 | 342, 494, 201, 957 |
| 3 | 171, 247, 201, 957 |
| 19 | 57, 247, 67, 319 |
| 3, 13, 67, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 3 x 13 x 67 x 319 = 190048716
Therefore, the lowest common multiple of 684,988,402,957 is 190048716.
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.
684 x 988 x 402 x 957 = 259986643488
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
402 : 1, 2, 3, 6, 67, 134, 201, 402
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,988,402,957, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
988:2x 2x 13x 19
402:2x 3x 67
957:3x 11x 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 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 259986643488/(1x1368)
LCM = 259986643488/1368
LCM = 190048716
Thus, we can understand that the LCM of 684,988,402,957 is 190048716.
