Given numbers are 298,242,418,342,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,242,418,342,356 is 1097533404.
Find LCM of 298,242,418,342,356 with Prime Factorization
| 2 | 298, 242, 418, 342, 356 |
| 11 | 149, 121, 209, 171, 178 |
| 19 | 149, 11, 19, 171, 178 |
| 149, 11, 1, 9, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 149 x 11 x 1 x 9 x 178 = 1097533404
Therefore, the lowest common multiple of 298,242,418,342,356 is 1097533404.
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.
298 x 242 x 418 x 342 x 356 = 3670151702976
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.
298 : 1, 2, 149, 298
242 : 1, 2, 11, 22, 121, 242
418 : 1, 2, 11, 19, 22, 38, 209, 418
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
356 : 1, 2, 4, 89, 178, 356
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,242,418,342,356, is 2.
Now, the common factors can be found like this.
298:2x 149
242:2x 11x 11
418:2x 11x 19
342:2x 3x 3x 19
356:2x 2x 89
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 11x 19 = 1672
Therefore, the value for common factors is 1672.
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 = 3670151702976/(2x1672)
LCM = 3670151702976/3344
LCM = 1097533404
Thus, we can understand that the LCM of 298,242,418,342,356 is 1097533404.
