Given numbers are 484,398,238,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,398,238,686 is 561618596.
Find LCM of 484,398,238,686 with Prime Factorization
| 2 | 484, 398, 238, 686 |
| 7 | 242, 199, 119, 343 |
| 242, 199, 17, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 242 x 199 x 17 x 49 = 561618596
Therefore, the lowest common multiple of 484,398,238,686 is 561618596.
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.
484 x 398 x 238 x 686 = 31450641376
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
398 : 1, 2, 199, 398
238 : 1, 2, 7, 14, 17, 34, 119, 238
686 : 1, 2, 7, 14, 49, 98, 343, 686
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,398,238,686, is 2.
Now, the common factors can be found like this.
484:2x 2x 11x 11
398:2x 199
238:2x 7x 17
686:2x 7x 7x 7
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 7 = 28
Therefore, the value for common factors is 28.
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 = 31450641376/(2x28)
LCM = 31450641376/56
LCM = 561618596
Thus, we can understand that the LCM of 484,398,238,686 is 561618596.
