Find LCM of 988,868,676,429 with Prime Factorization
| 2 | 988, 868, 676, 429 |
| 2 | 494, 434, 338, 429 |
| 13 | 247, 217, 169, 429 |
| 19, 217, 13, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 217 x 13 x 33 = 91975884
Therefore, the lowest common multiple of 988,868,676,429 is 91975884.
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 868 x 676 x 429 = 248702790336
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
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,868,676,429, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
868:2x 2x 7x 31
676:2x 2x 13x 13
429:3x 11x 13
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 13x 13 = 2704
Therefore, the value for common factors is 2704.
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 = 248702790336/(1x2704)
LCM = 248702790336/2704
LCM = 91975884
Thus, we can understand that the LCM of 988,868,676,429 is 91975884.
