Find the LCM of 197, 743, 197, 639 with the LCM of Two or More Numbers Calculator. Here we are teaching you two different methods through which you can calculate the LCM of 197, 743, 197, 639. So, keep reading to learn more.
Given numbers are 197,743,197,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,743,197,639 is 93531069.
Find LCM of 197,743,197,639 with Prime Factorization
197 | 197, 743, 197, 639 |
1, 743, 1, 639 |
Multiply the prime numbers at the bottom and the left side.
197 x 1 x 743 x 1 x 639 = 93531069
Therefore, the lowest common multiple of 197,743,197,639 is 93531069.
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 743 x 197 x 639 = 18425620593
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
743 : 1, 743
197 : 1, 197
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,743,197,639, is 1.
Now, the common factors can be found like this.
197:197
743:743
197:197
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
197 = 197
Therefore, the value for common factors is 197.
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 = 18425620593/(1x197)
LCM = 18425620593/197
LCM = 93531069
Thus, we can understand that the LCM of 197,743,197,639 is 93531069.
