Given numbers are 509,663,126,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 509,663,126,728 is 56694456.
Find LCM of 509,663,126,728 with Prime Factorization
| 2 | 509, 663, 126, 728 |
| 3 | 509, 663, 63, 364 |
| 7 | 509, 221, 21, 364 |
| 13 | 509, 221, 3, 52 |
| 509, 17, 3, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 509 x 17 x 3 x 4 = 56694456
Therefore, the lowest common multiple of 509,663,126,728 is 56694456.
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.
509 x 663 x 126 x 728 = 30955172976
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.
509 : 1, 509
663 : 1, 3, 13, 17, 39, 51, 221, 663
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,663,126,728, is 1.
Now, the common factors can be found like this.
509:509
663:3x 13x 17
126:2x 3x 3x 7
728:2x 2x 2x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 13 = 546
Therefore, the value for common factors is 546.
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 = 30955172976/(1x546)
LCM = 30955172976/546
LCM = 56694456
Thus, we can understand that the LCM of 509,663,126,728 is 56694456.
