Given numbers are 633,128,211,405

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

The LCM of 633,128,211,405 is 10938240.

Find LCM of 633,128,211,405 with Prime Factorization

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

3 x 211 x 1 x 128 x 1 x 135 = 10938240

Therefore, the lowest common multiple of 633,128,211,405 is 10938240.

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.

633 x 128 x 211 x 405 = 6923905920

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.

633 : 1, 3, 211, 633

128 : 1, 2, 4, 8, 16, 32, 64, 128

211 : 1, 211

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 633,128,211,405, is 1.

Now, the common factors can be found like this.

633:3x 211

128:2x 2x 2x 2x 2x 2x 2

211:211

405:3x 3x 3x 3x 5

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

3x 211 = 633

Therefore, the value for common factors is 633.

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 = 6923905920/(1x633)

LCM = 6923905920/633

LCM = 10938240

Thus, we can understand that the LCM of 633,128,211,405 is 10938240.
