Given numbers are 561,136,422,521

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

The LCM of 561,136,422,521 is 493370328.

Find LCM of 561,136,422,521 with Prime Factorization

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

2 x 17 x 33 x 4 x 211 x 521 = 493370328

Therefore, the lowest common multiple of 561,136,422,521 is 493370328.

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.

561 x 136 x 422 x 521 = 16774591152

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

136 : 1, 2, 4, 8, 17, 34, 68, 136

422 : 1, 2, 211, 422

521 : 1, 521

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,136,422,521, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

136:2x 2x 2x 17

422:2x 211

521:521

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 16774591152/(1x34)

LCM = 16774591152/34

LCM = 493370328

Thus, we can understand that the LCM of 561,136,422,521 is 493370328.
