Given numbers are 111,986,161,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 111,986,161,493 is 17620806.
Find LCM of 111,986,161,493 with Prime Factorization
| 17 | 111, 986, 161, 493 |
| 29 | 111, 58, 161, 29 |
| 111, 2, 161, 1 |
Multiply the prime numbers at the bottom and the left side.
17 x 29 x 111 x 2 x 161 x 1 = 17620806
Therefore, the lowest common multiple of 111,986,161,493 is 17620806.
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.
111 x 986 x 161 x 493 = 8687057358
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.
111 : 1, 3, 37, 111
986 : 1, 2, 17, 29, 34, 58, 493, 986
161 : 1, 7, 23, 161
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 111,986,161,493, is 1.
Now, the common factors can be found like this.
111:3x 37
986:2x 17x 29
161:7x 23
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 29 = 493
Therefore, the value for common factors is 493.
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 = 8687057358/(1x493)
LCM = 8687057358/493
LCM = 17620806
Thus, we can understand that the LCM of 111,986,161,493 is 17620806.
