Given numbers are 397,731,678,964,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,731,678,964,872 is 20674790116296.
Find LCM of 397,731,678,964,872 with Prime Factorization
2 | 397, 731, 678, 964, 872 |
2 | 397, 731, 339, 482, 436 |
397, 731, 339, 241, 218 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 397 x 731 x 339 x 241 x 218 = 20674790116296
Therefore, the lowest common multiple of 397,731,678,964,872 is 20674790116296.
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.
397 x 731 x 678 x 964 x 872 = 165398320930368
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.
397 : 1, 397
731 : 1, 17, 43, 731
678 : 1, 2, 3, 6, 113, 226, 339, 678
964 : 1, 2, 4, 241, 482, 964
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,731,678,964,872, is 1.
Now, the common factors can be found like this.
397:397
731:17x 43
678:2x 3x 113
964:2x 2x 241
872:2x 2x 2x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 165398320930368/(1x8)
LCM = 165398320930368/8
LCM = 20674790116296
Thus, we can understand that the LCM of 397,731,678,964,872 is 20674790116296.
