Given numbers are 281,403,323,455

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

The LCM of 281,403,323,455 is 1280212115.

Find LCM of 281,403,323,455 with Prime Factorization

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

13 x 281 x 31 x 323 x 35 = 1280212115

Therefore, the lowest common multiple of 281,403,323,455 is 1280212115.

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 403 x 323 x 455 = 16642757495

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

403 : 1, 13, 31, 403

323 : 1, 17, 19, 323

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,403,323,455, is 1.

Now, the common factors can be found like this.

281:281

403:13x 31

323:17x 19

455:5x 7x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 16642757495/(1x13)

LCM = 16642757495/13

LCM = 1280212115

Thus, we can understand that the LCM of 281,403,323,455 is 1280212115.
