Given numbers are 505,574,462,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,574,462,538 is 2573175990.
Find LCM of 505,574,462,538 with Prime Factorization
| 2 | 505, 574, 462, 538 |
| 7 | 505, 287, 231, 269 |
| 505, 41, 33, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 505 x 41 x 33 x 269 = 2573175990
Therefore, the lowest common multiple of 505,574,462,538 is 2573175990.
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.
505 x 574 x 462 x 538 = 72048927720
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.
505 : 1, 5, 101, 505
574 : 1, 2, 7, 14, 41, 82, 287, 574
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,574,462,538, is 1.
Now, the common factors can be found like this.
505:5x 101
574:2x 7x 41
462:2x 3x 7x 11
538:2x 269
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 = 72048927720/(1x28)
LCM = 72048927720/28
LCM = 2573175990
Thus, we can understand that the LCM of 505,574,462,538 is 2573175990.
