Given numbers are 197,841,957,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,841,957,143 is 71075433.
Find LCM of 197,841,957,143 with Prime Factorization
11 | 197, 841, 957, 143 |
29 | 197, 841, 87, 13 |
197, 29, 3, 13 |
Multiply the prime numbers at the bottom and the left side.
11 x 29 x 197 x 29 x 3 x 13 = 71075433
Therefore, the lowest common multiple of 197,841,957,143 is 71075433.
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.
197 x 841 x 957 x 143 = 22673063127
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.
197 : 1, 197
841 : 1, 29, 841
957 : 1, 3, 11, 29, 33, 87, 319, 957
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,841,957,143, is 1.
Now, the common factors can be found like this.
197:197
841:29x 29
957:3x 11x 29
143:11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 29 = 319
Therefore, the value for common factors is 319.
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 = 22673063127/(1x319)
LCM = 22673063127/319
LCM = 71075433
Thus, we can understand that the LCM of 197,841,957,143 is 71075433.
