Given numbers are 398,422,169,729
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,422,169,729 is 10346173578.
Find LCM of 398,422,169,729 with Prime Factorization
2 | 398, 422, 169, 729 |
199, 211, 169, 729 |
Multiply the prime numbers at the bottom and the left side.
2 x 199 x 211 x 169 x 729 = 10346173578
Therefore, the lowest common multiple of 398,422,169,729 is 10346173578.
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.
398 x 422 x 169 x 729 = 20692347156
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.
398 : 1, 2, 199, 398
422 : 1, 2, 211, 422
169 : 1, 13, 169
729 : 1, 3, 9, 27, 81, 243, 729
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,422,169,729, is 1.
Now, the common factors can be found like this.
398:2x 199
422:2x 211
169:13x 13
729:3x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 20692347156/(1x2)
LCM = 20692347156/2
LCM = 10346173578
Thus, we can understand that the LCM of 398,422,169,729 is 10346173578.
