Given numbers are 106,161,690,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 106,161,690,917 is 33534690.
Find LCM of 106,161,690,917 with Prime Factorization
| 2 | 106, 161, 690, 917 |
| 7 | 53, 161, 345, 917 |
| 23 | 53, 23, 345, 131 |
| 53, 1, 15, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 53 x 1 x 15 x 131 = 33534690
Therefore, the lowest common multiple of 106,161,690,917 is 33534690.
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.
106 x 161 x 690 x 917 = 10798170180
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.
106 : 1, 2, 53, 106
161 : 1, 7, 23, 161
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 106,161,690,917, is 1.
Now, the common factors can be found like this.
106:2x 53
161:7x 23
690:2x 3x 5x 23
917:7x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 23 = 322
Therefore, the value for common factors is 322.
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 = 10798170180/(1x322)
LCM = 10798170180/322
LCM = 33534690
Thus, we can understand that the LCM of 106,161,690,917 is 33534690.
