The LCM of 634,818,988,988 is 128097164.
Find LCM of 634,818,988,988 with Prime Factorization
| 2 | 634, 818, 988, 988 |
| 2 | 317, 409, 494, 494 |
| 13 | 317, 409, 247, 247 |
| 19 | 317, 409, 19, 19 |
| 317, 409, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 317 x 409 x 1 x 1 = 128097164
Therefore, the lowest common multiple of 634,818,988,988 is 128097164.
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.
634 x 818 x 988 x 988 = 506239992128
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.
634 : 1, 2, 317, 634
818 : 1, 2, 409, 818
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,818,988,988, is 2.
Now, the common factors can be found like this.
634:2x 317
818:2x 409
988:2x 2x 13x 19
988:2x 2x 13x 19
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 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 506239992128/(2x1976)
LCM = 506239992128/3952
LCM = 128097164
Thus, we can understand that the LCM of 634,818,988,988 is 128097164.
