Find LCM of 989,328,897,936 with Prime Factorization
| 2 | 989, 328, 897, 936 |
| 2 | 989, 164, 897, 468 |
| 2 | 989, 82, 897, 234 |
| 3 | 989, 41, 897, 117 |
| 13 | 989, 41, 299, 39 |
| 23 | 989, 41, 23, 3 |
| 43, 41, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 23 x 43 x 41 x 1 x 3 = 37953864
Therefore, the lowest common multiple of 989,328,897,936 is 37953864.
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.
989 x 328 x 897 x 936 = 272356928064
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.
989 : 1, 23, 43, 989
328 : 1, 2, 4, 8, 41, 82, 164, 328
897 : 1, 3, 13, 23, 39, 69, 299, 897
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,328,897,936, is 1.
Now, the common factors can be found like this.
989:23x 43
328:2x 2x 2x 41
897:3x 13x 23
936:2x 2x 2x 3x 3x 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 3x 13x 23 = 7176
Therefore, the value for common factors is 7176.
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 = 272356928064/(1x7176)
LCM = 272356928064/7176
LCM = 37953864
Thus, we can understand that the LCM of 989,328,897,936 is 37953864.
