Given numbers are 174,261,138,160,347
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 174,261,138,160,347 is 333286560.
Find LCM of 174,261,138,160,347 with Prime Factorization
| 2 | 174, 261, 138, 160, 347 |
| 3 | 87, 261, 69, 80, 347 |
| 29 | 29, 87, 23, 80, 347 |
| 1, 3, 23, 80, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 1 x 3 x 23 x 80 x 347 = 333286560
Therefore, the lowest common multiple of 174,261,138,160,347 is 333286560.
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.
174 x 261 x 138 x 160 x 347 = 347951168640
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.
174 : 1, 2, 3, 6, 29, 58, 87, 174
261 : 1, 3, 9, 29, 87, 261
138 : 1, 2, 3, 6, 23, 46, 69, 138
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,261,138,160,347, is 1.
Now, the common factors can be found like this.
174:2x 3x 29
261:3x 3x 29
138:2x 3x 23
160:2x 2x 2x 2x 2x 5
347:347
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 3x 3x 29 = 1044
Therefore, the value for common factors is 1044.
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 = 347951168640/(1x1044)
LCM = 347951168640/1044
LCM = 333286560
Thus, we can understand that the LCM of 174,261,138,160,347 is 333286560.
