Given numbers are 308,442,422,692,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 308,442,422,692,121 is 27331548244.
Find LCM of 308,442,422,692,121 with Prime Factorization
| 2 | 308, 442, 422, 692, 121 |
| 2 | 154, 221, 211, 346, 121 |
| 11 | 77, 221, 211, 173, 121 |
| 7, 221, 211, 173, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 7 x 221 x 211 x 173 x 11 = 27331548244
Therefore, the lowest common multiple of 308,442,422,692,121 is 27331548244.
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.
308 x 442 x 422 x 692 x 121 = 4810352490944
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
442 : 1, 2, 13, 17, 26, 34, 221, 442
422 : 1, 2, 211, 422
692 : 1, 2, 4, 173, 346, 692
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,442,422,692,121, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
442:2x 13x 17
422:2x 211
692:2x 2x 173
121:11x 11
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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 4810352490944/(1x176)
LCM = 4810352490944/176
LCM = 27331548244
Thus, we can understand that the LCM of 308,442,422,692,121 is 27331548244.
