The LCM of 988,772,874,878,649 is 1249543289852.
Find LCM of 988,772,874,878,649 with Prime Factorization
| 2 | 988, 772, 874, 878, 649 |
| 2 | 494, 386, 437, 439, 649 |
| 19 | 247, 193, 437, 439, 649 |
| 13, 193, 23, 439, 649 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 13 x 193 x 23 x 439 x 649 = 1249543289852
Therefore, the lowest common multiple of 988,772,874,878,649 is 1249543289852.
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.
988 x 772 x 874 x 878 x 649 = 379861160115008
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
772 : 1, 2, 4, 193, 386, 772
874 : 1, 2, 19, 23, 38, 46, 437, 874
878 : 1, 2, 439, 878
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,772,874,878,649, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
772:2x 2x 193
874:2x 19x 23
878:2x 439
649:11x 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 2x 2x 19 = 304
Therefore, the value for common factors is 304.
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 = 379861160115008/(1x304)
LCM = 379861160115008/304
LCM = 1249543289852
Thus, we can understand that the LCM of 988,772,874,878,649 is 1249543289852.
