Find LCM of 996,678,989,979,644 with Prime Factorization
| 2 | 996, 678, 989, 979, 644 |
| 2 | 498, 339, 989, 979, 322 |
| 3 | 249, 339, 989, 979, 161 |
| 23 | 83, 113, 989, 979, 161 |
| 83, 113, 43, 979, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 83 x 113 x 43 x 979 x 7 = 762807238116
Therefore, the lowest common multiple of 996,678,989,979,644 is 762807238116.
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.
996 x 678 x 989 x 979 x 644 = 421069595440032
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.
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
678 : 1, 2, 3, 6, 113, 226, 339, 678
989 : 1, 23, 43, 989
979 : 1, 11, 89, 979
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 996,678,989,979,644, is 1.
Now, the common factors can be found like this.
996:2x 2x 3x 83
678:2x 3x 113
989:23x 43
979:11x 89
644:2x 2x 7x 23
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 23 = 552
Therefore, the value for common factors is 552.
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 = 421069595440032/(1x552)
LCM = 421069595440032/552
LCM = 762807238116
Thus, we can understand that the LCM of 996,678,989,979,644 is 762807238116.
