Given numbers are 561,455,253,409

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

The LCM of 561,455,253,409 is 2401183785.

Find LCM of 561,455,253,409 with Prime Factorization

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

11 x 51 x 455 x 23 x 409 = 2401183785

Therefore, the lowest common multiple of 561,455,253,409 is 2401183785.

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 455 x 253 x 409 = 26413021635

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

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

253 : 1, 11, 23, 253

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,455,253,409, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

455:5x 7x 13

253:11x 23

409:409

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

11 = 11

Therefore, the value for common factors is 11.

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 = 26413021635/(1x11)

LCM = 26413021635/11

LCM = 2401183785

Thus, we can understand that the LCM of 561,455,253,409 is 2401183785.
