Given numbers are 289,247,221,621

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

The LCM of 289,247,221,621 is 44328843.

Find LCM of 289,247,221,621 with Prime Factorization

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

13 x 17 x 1 x 19 x 17 x 621 = 44328843

Therefore, the lowest common multiple of 289,247,221,621 is 44328843.

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.

289 x 247 x 221 x 621 = 9796674303

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.

289 : 1, 17, 289

247 : 1, 13, 19, 247

221 : 1, 13, 17, 221

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,247,221,621, is 1.

Now, the common factors can be found like this.

289:17x 17

247:13x 19

221:13x 17

621:3x 3x 3x 23

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

13x 17 = 221

Therefore, the value for common factors is 221.

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 = 9796674303/(1x221)

LCM = 9796674303/221

LCM = 44328843

Thus, we can understand that the LCM of 289,247,221,621 is 44328843.
