Given numbers are 455,273,221,168,683

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

The LCM of 455,273,221,168,683 is 126792120.

Find LCM of 455,273,221,168,683 with Prime Factorization

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

3 x 7 x 13 x 5 x 1 x 17 x 8 x 683 = 126792120

Therefore, the lowest common multiple of 455,273,221,168,683 is 126792120.

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.

455 x 273 x 221 x 168 x 683 = 3149896637160

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.

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

273 : 1, 3, 7, 13, 21, 39, 91, 273

221 : 1, 13, 17, 221

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

683 : 1, 683

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,273,221,168,683, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

273:3x 7x 13

221:13x 17

168:2x 2x 2x 3x 7

683:683

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

3x 7x 7x 13x 13 = 24843

Therefore, the value for common factors is 24843.

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 = 3149896637160/(1x24843)

LCM = 3149896637160/24843

LCM = 126792120

Thus, we can understand that the LCM of 455,273,221,168,683 is 126792120.
