Given numbers are 515,394,197,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,394,197,991 is 201083810.
Find LCM of 515,394,197,991 with Prime Factorization
197 | 515, 394, 197, 991 |
515, 2, 1, 991 |
Multiply the prime numbers at the bottom and the left side.
197 x 515 x 2 x 1 x 991 = 201083810
Therefore, the lowest common multiple of 515,394,197,991 is 201083810.
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.
515 x 394 x 197 x 991 = 39613510570
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.
515 : 1, 5, 103, 515
394 : 1, 2, 197, 394
197 : 1, 197
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,394,197,991, is 1.
Now, the common factors can be found like this.
515:5x 103
394:2x 197
197:197
991:991
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 = 39613510570/(1x197)
LCM = 39613510570/197
LCM = 201083810
Thus, we can understand that the LCM of 515,394,197,991 is 201083810.
