Given numbers are 855,731,281,281
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,731,281,281 is 175626405.
Find LCM of 855,731,281,281 with Prime Factorization
281 | 855, 731, 281, 281 |
855, 731, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
281 x 855 x 731 x 1 x 1 = 175626405
Therefore, the lowest common multiple of 855,731,281,281 is 175626405.
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.
855 x 731 x 281 x 281 = 49351019805
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
731 : 1, 17, 43, 731
281 : 1, 281
281 : 1, 281
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,731,281,281, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
731:17x 43
281:281
281:281
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
281 = 281
Therefore, the value for common factors is 281.
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 = 49351019805/(1x281)
LCM = 49351019805/281
LCM = 175626405
Thus, we can understand that the LCM of 855,731,281,281 is 175626405.
