Given numbers are 281,260,455,163

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 281,260,455,163 is 83361460.

Find LCM of 281,260,455,163 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

5 x 13 x 281 x 4 x 7 x 163 = 83361460

Therefore, the lowest common multiple of 281,260,455,163 is 83361460.

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.

281 x 260 x 455 x 163 = 5418494900

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.

281 : 1, 281

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

455 : 1, 5, 7, 13, 35, 65, 91, 455

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,260,455,163, is 1.

Now, the common factors can be found like this.

281:281

260:2x 2x 5x 13

455:5x 7x 13

163:163

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 13 = 65

Therefore, the value for common factors is 65.

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 = 5418494900/(1x65)

LCM = 5418494900/65

LCM = 83361460

Thus, we can understand that the LCM of 281,260,455,163 is 83361460.
