Given numbers are 443,783,672,921,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 443,783,672,921,399 is 453216260448.
Find LCM of 443,783,672,921,399 with Prime Factorization
| 3 | 443, 783, 672, 921, 399 |
| 7 | 443, 261, 224, 307, 133 |
| 443, 261, 32, 307, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 443 x 261 x 32 x 307 x 19 = 453216260448
Therefore, the lowest common multiple of 443,783,672,921,399 is 453216260448.
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.
443 x 783 x 672 x 921 x 399 = 85657873224672
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.
443 : 1, 443
783 : 1, 3, 9, 27, 29, 87, 261, 783
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
921 : 1, 3, 307, 921
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,783,672,921,399, is 1.
Now, the common factors can be found like this.
443:443
783:3x 3x 3x 29
672:2x 2x 2x 2x 2x 3x 7
921:3x 307
399:3x 7x 19
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 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 85657873224672/(1x189)
LCM = 85657873224672/189
LCM = 453216260448
Thus, we can understand that the LCM of 443,783,672,921,399 is 453216260448.
