Find LCM of 540,281,405,428 with Prime Factorization
| 2 | 540, 281, 405, 428 |
| 2 | 270, 281, 405, 214 |
| 3 | 135, 281, 405, 107 |
| 3 | 45, 281, 135, 107 |
| 3 | 15, 281, 45, 107 |
| 5 | 5, 281, 15, 107 |
| 1, 281, 3, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 1 x 281 x 3 x 107 = 48708540
Therefore, the lowest common multiple of 540,281,405,428 is 48708540.
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.
540 x 281 x 405 x 428 = 26302611600
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.
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
281 : 1, 281
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 540,281,405,428, is 1.
Now, the common factors can be found like this.
540:2x 2x 3x 3x 3x 5
281:281
405:3x 3x 3x 3x 5
428:2x 2x 107
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 26302611600/(1x540)
LCM = 26302611600/540
LCM = 48708540
Thus, we can understand that the LCM of 540,281,405,428 is 48708540.
