Given numbers are 201,638,201,431

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

The LCM of 201,638,201,431 is 55270578.

Find LCM of 201,638,201,431 with Prime Factorization

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

3 x 67 x 1 x 638 x 1 x 431 = 55270578

Therefore, the lowest common multiple of 201,638,201,431 is 55270578.

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.

201 x 638 x 201 x 431 = 11109386178

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.

201 : 1, 3, 67, 201

638 : 1, 2, 11, 22, 29, 58, 319, 638

201 : 1, 3, 67, 201

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 201,638,201,431, is 1.

Now, the common factors can be found like this.

201:3x 67

638:2x 11x 29

201:3x 67

431:431

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

3x 67 = 201

Therefore, the value for common factors is 201.

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 = 11109386178/(1x201)

LCM = 11109386178/201

LCM = 55270578

Thus, we can understand that the LCM of 201,638,201,431 is 55270578.
