Given numbers are 902,913,197,389,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,913,197,389,243 is 1394141101254.
Find LCM of 902,913,197,389,243 with Prime Factorization
| 11 | 902, 913, 197, 389, 243 |
| 82, 83, 197, 389, 243 |
Multiply the prime numbers at the bottom and the left side.
11 x 82 x 83 x 197 x 389 x 243 = 1394141101254
Therefore, the lowest common multiple of 902,913,197,389,243 is 1394141101254.
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.
902 x 913 x 197 x 389 x 243 = 15335552113794
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
913 : 1, 11, 83, 913
197 : 1, 197
389 : 1, 389
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,913,197,389,243, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
913:11x 83
197:197
389:389
243:3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 15335552113794/(1x11)
LCM = 15335552113794/11
LCM = 1394141101254
Thus, we can understand that the LCM of 902,913,197,389,243 is 1394141101254.
