Given numbers are 253,957,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,957,198 is 132066.
Find LCM of 253,957,198 with Prime Factorization
| 3 | 253, 957, 198 |
| 11 | 253, 319, 66 |
| 23, 29, 6 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 29 x 6 = 132066
Therefore, the lowest common multiple of 253,957,198 is 132066.
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.
253 x 957 x 198 = 47939958
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.
253 : 1, 11, 23, 253
957 : 1, 3, 11, 29, 33, 87, 319, 957
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,957,198, is 11.
Now, the common factors can be found like this.
253:11x 23
957:3x 11x 29
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 47939958/(11x33)
LCM = 47939958/363
LCM = 132066
Thus, we can understand that the LCM of 253,957,198 is 132066.
