Given numbers are 672,663,993,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,663,993,984 is 2015456352.
Find LCM of 672,663,993,984 with Prime Factorization
| 2 | 672, 663, 993, 984 |
| 2 | 336, 663, 993, 492 |
| 2 | 168, 663, 993, 246 |
| 3 | 84, 663, 993, 123 |
| 28, 221, 331, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 28 x 221 x 331 x 41 = 2015456352
Therefore, the lowest common multiple of 672,663,993,984 is 2015456352.
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.
672 x 663 x 993 x 984 = 435338572032
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.
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
663 : 1, 3, 13, 17, 39, 51, 221, 663
993 : 1, 3, 331, 993
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,663,993,984, is 3.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
663:3x 13x 17
993:3x 331
984:2x 2x 2x 3x 41
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 3 = 72
Therefore, the value for common factors is 72.
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 = 435338572032/(3x72)
LCM = 435338572032/216
LCM = 2015456352
Thus, we can understand that the LCM of 672,663,993,984 is 2015456352.
