Find LCM of 987,996,408,178,903 with Prime Factorization
2 | 987, 996, 408, 178, 903 |
2 | 987, 498, 204, 89, 903 |
3 | 987, 249, 102, 89, 903 |
7 | 329, 83, 34, 89, 301 |
47, 83, 34, 89, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 47 x 83 x 34 x 89 x 43 = 42637586712
Therefore, the lowest common multiple of 987,996,408,178,903 is 42637586712.
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.
987 x 996 x 408 x 178 x 903 = 64468031108544
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
178 : 1, 2, 89, 178
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,996,408,178,903, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
996:2x 2x 3x 83
408:2x 2x 2x 3x 17
178:2x 89
903:3x 7x 43
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 3x 7 = 1512
Therefore, the value for common factors is 1512.
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 = 64468031108544/(1x1512)
LCM = 64468031108544/1512
LCM = 42637586712
Thus, we can understand that the LCM of 987,996,408,178,903 is 42637586712.
