Given numbers are 489,308,364,548
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,308,364,548 is 268239972.
Find LCM of 489,308,364,548 with Prime Factorization
| 2 | 489, 308, 364, 548 |
| 2 | 489, 154, 182, 274 |
| 7 | 489, 77, 91, 137 |
| 489, 11, 13, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 489 x 11 x 13 x 137 = 268239972
Therefore, the lowest common multiple of 489,308,364,548 is 268239972.
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.
489 x 308 x 364 x 548 = 30042876864
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.
489 : 1, 3, 163, 489
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
548 : 1, 2, 4, 137, 274, 548
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,308,364,548, is 1.
Now, the common factors can be found like this.
489:3x 163
308:2x 2x 7x 11
364:2x 2x 7x 13
548:2x 2x 137
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 7 = 112
Therefore, the value for common factors is 112.
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 = 30042876864/(1x112)
LCM = 30042876864/112
LCM = 268239972
Thus, we can understand that the LCM of 489,308,364,548 is 268239972.
