Given numbers are 997,974,397,794
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 997,974,397,794 is 385517966.
Find LCM of 997,974,397,794 with Prime Factorization
| 2 | 997, 974, 397, 794 |
| 397 | 997, 487, 397, 397 |
| 997, 487, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 397 x 997 x 487 x 1 x 1 = 385517966
Therefore, the lowest common multiple of 997,974,397,794 is 385517966.
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.
997 x 974 x 397 x 794 = 306101265004
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.
997 : 1, 997
974 : 1, 2, 487, 974
397 : 1, 397
794 : 1, 2, 397, 794
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,974,397,794, is 1.
Now, the common factors can be found like this.
997:997
974:2x 487
397:397
794:2x 397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 397 = 794
Therefore, the value for common factors is 794.
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 = 306101265004/(1x794)
LCM = 306101265004/794
LCM = 385517966
Thus, we can understand that the LCM of 997,974,397,794 is 385517966.
