Given numbers are 813,270,261,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,270,261,545 is 231290370.
Find LCM of 813,270,261,545 with Prime Factorization
3 | 813, 270, 261, 545 |
3 | 271, 90, 87, 545 |
5 | 271, 30, 29, 545 |
271, 6, 29, 109 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 271 x 6 x 29 x 109 = 231290370
Therefore, the lowest common multiple of 813,270,261,545 is 231290370.
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.
813 x 270 x 261 x 545 = 31224199950
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.
813 : 1, 3, 271, 813
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
261 : 1, 3, 9, 29, 87, 261
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,270,261,545, is 1.
Now, the common factors can be found like this.
813:3x 271
270:2x 3x 3x 3x 5
261:3x 3x 29
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 31224199950/(1x135)
LCM = 31224199950/135
LCM = 231290370
Thus, we can understand that the LCM of 813,270,261,545 is 231290370.
