Given numbers are 122,634,189,361
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 122,634,189,361 is 2638688346.
Find LCM of 122,634,189,361 with Prime Factorization
| 2 | 122, 634, 189, 361 |
| 61, 317, 189, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 61 x 317 x 189 x 361 = 2638688346
Therefore, the lowest common multiple of 122,634,189,361 is 2638688346.
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.
122 x 634 x 189 x 361 = 5277376692
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.
122 : 1, 2, 61, 122
634 : 1, 2, 317, 634
189 : 1, 3, 7, 9, 21, 27, 63, 189
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,634,189,361, is 1.
Now, the common factors can be found like this.
122:2x 61
634:2x 317
189:3x 3x 3x 7
361:19x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 5277376692/(1x2)
LCM = 5277376692/2
LCM = 2638688346
Thus, we can understand that the LCM of 122,634,189,361 is 2638688346.
