Given numbers are 997,872,872,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 997,872,872,638 is 277333496.
Find LCM of 997,872,872,638 with Prime Factorization
| 2 | 997, 872, 872, 638 |
| 2 | 997, 436, 436, 319 |
| 2 | 997, 218, 218, 319 |
| 109 | 997, 109, 109, 319 |
| 997, 1, 1, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 109 x 997 x 1 x 1 x 319 = 277333496
Therefore, the lowest common multiple of 997,872,872,638 is 277333496.
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 872 x 872 x 638 = 483669617024
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
872 : 1, 2, 4, 8, 109, 218, 436, 872
872 : 1, 2, 4, 8, 109, 218, 436, 872
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,872,872,638, is 1.
Now, the common factors can be found like this.
997:997
872:2x 2x 2x 109
872:2x 2x 2x 109
638:2x 11x 29
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 2x 2x 109 = 1744
Therefore, the value for common factors is 1744.
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 = 483669617024/(1x1744)
LCM = 483669617024/1744
LCM = 277333496
Thus, we can understand that the LCM of 997,872,872,638 is 277333496.
