Given numbers are 421,411,981,552,161

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

The LCM of 421,411,981,552,161 is 72876504456.

Find LCM of 421,411,981,552,161 with Prime Factorization

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

3 x 23 x 421 x 137 x 327 x 8 x 7 = 72876504456

Therefore, the lowest common multiple of 421,411,981,552,161 is 72876504456.

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.

421 x 411 x 981 x 552 x 161 = 15085436422392

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.

421 : 1, 421

411 : 1, 3, 137, 411

981 : 1, 3, 9, 109, 327, 981

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,411,981,552,161, is 1.

Now, the common factors can be found like this.

421:421

411:3x 137

981:3x 3x 109

552:2x 2x 2x 3x 23

161:7x 23

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 23 = 207

Therefore, the value for common factors is 207.

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 = 15085436422392/(1x207)

LCM = 15085436422392/207

LCM = 72876504456

Thus, we can understand that the LCM of 421,411,981,552,161 is 72876504456.
