Given numbers are 997,806,673,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 997,806,673,442 is 9193781662.
Find LCM of 997,806,673,442 with Prime Factorization
| 2 | 997, 806, 673, 442 |
| 13 | 997, 403, 673, 221 |
| 997, 31, 673, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 997 x 31 x 673 x 17 = 9193781662
Therefore, the lowest common multiple of 997,806,673,442 is 9193781662.
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 806 x 673 x 442 = 239038323212
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
673 : 1, 673
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,806,673,442, is 1.
Now, the common factors can be found like this.
997:997
806:2x 13x 31
673:673
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 239038323212/(1x26)
LCM = 239038323212/26
LCM = 9193781662
Thus, we can understand that the LCM of 997,806,673,442 is 9193781662.
