Given numbers are 548,142,928,530,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 548,142,928,530,981 is 2346614627040.
Find LCM of 548,142,928,530,981 with Prime Factorization
| 2 | 548, 142, 928, 530, 981 |
| 2 | 274, 71, 464, 265, 981 |
| 137, 71, 232, 265, 981 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 137 x 71 x 232 x 265 x 981 = 2346614627040
Therefore, the lowest common multiple of 548,142,928,530,981 is 2346614627040.
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.
548 x 142 x 928 x 530 x 981 = 37545834032640
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.
548 : 1, 2, 4, 137, 274, 548
142 : 1, 2, 71, 142
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
530 : 1, 2, 5, 10, 53, 106, 265, 530
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,142,928,530,981, is 1.
Now, the common factors can be found like this.
548:2x 2x 137
142:2x 71
928:2x 2x 2x 2x 2x 29
530:2x 5x 53
981:3x 3x 109
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 2 = 16
Therefore, the value for common factors is 16.
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 = 37545834032640/(1x16)
LCM = 37545834032640/16
LCM = 2346614627040
Thus, we can understand that the LCM of 548,142,928,530,981 is 2346614627040.
