Given numbers are 171,499,691,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 171,499,691,993 is 19516534209.
Find LCM of 171,499,691,993 with Prime Factorization
3 | 171, 499, 691, 993 |
57, 499, 691, 331 |
Multiply the prime numbers at the bottom and the left side.
3 x 57 x 499 x 691 x 331 = 19516534209
Therefore, the lowest common multiple of 171,499,691,993 is 19516534209.
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.
171 x 499 x 691 x 993 = 58549602627
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.
171 : 1, 3, 9, 19, 57, 171
499 : 1, 499
691 : 1, 691
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,499,691,993, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
499:499
691:691
993:3x 331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 58549602627/(1x3)
LCM = 58549602627/3
LCM = 19516534209
Thus, we can understand that the LCM of 171,499,691,993 is 19516534209.
