Given numbers are 257,663,901,585
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,663,901,585 is 135460845.
Find LCM of 257,663,901,585 with Prime Factorization
| 3 | 257, 663, 901, 585 |
| 13 | 257, 221, 901, 195 |
| 17 | 257, 17, 901, 15 |
| 257, 1, 53, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 257 x 1 x 53 x 15 = 135460845
Therefore, the lowest common multiple of 257,663,901,585 is 135460845.
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.
257 x 663 x 901 x 585 = 89810540235
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.
257 : 1, 257
663 : 1, 3, 13, 17, 39, 51, 221, 663
901 : 1, 17, 53, 901
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,663,901,585, is 1.
Now, the common factors can be found like this.
257:257
663:3x 13x 17
901:17x 53
585:3x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 17 = 663
Therefore, the value for common factors is 663.
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 = 89810540235/(1x663)
LCM = 89810540235/663
LCM = 135460845
Thus, we can understand that the LCM of 257,663,901,585 is 135460845.
