Given numbers are 621,161,612,321,305

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

The LCM of 621,161,612,321,305 is 9646775460.

Find LCM of 621,161,612,321,305 with Prime Factorization

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

3 x 3 x 23 x 3 x 7 x 68 x 107 x 305 = 9646775460

Therefore, the lowest common multiple of 621,161,612,321,305 is 9646775460.

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.

621 x 161 x 612 x 321 x 305 = 5990647560660

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

161 : 1, 7, 23, 161

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

321 : 1, 3, 107, 321

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,161,612,321,305, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

161:7x 23

612:2x 2x 3x 3x 17

321:3x 107

305:5x 61

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 23 = 621

Therefore, the value for common factors is 621.

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 = 5990647560660/(1x621)

LCM = 5990647560660/621

LCM = 9646775460

Thus, we can understand that the LCM of 621,161,612,321,305 is 9646775460.
