Given numbers are 672,867,879,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 672,867,879,189 is 512126496.
Find LCM of 672,867,879,189 with Prime Factorization
| 3 | 672, 867, 879, 189 |
| 7 | 224, 289, 293, 63 |
| 32, 289, 293, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 32 x 289 x 293 x 9 = 512126496
Therefore, the lowest common multiple of 672,867,879,189 is 512126496.
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 867 x 879 x 189 = 96791907744
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
867 : 1, 3, 17, 51, 289, 867
879 : 1, 3, 293, 879
189 : 1, 3, 7, 9, 21, 27, 63, 189
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,867,879,189, is 3.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
867:3x 17x 17
879:3x 293
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 96791907744/(3x63)
LCM = 96791907744/189
LCM = 512126496
Thus, we can understand that the LCM of 672,867,879,189 is 512126496.
