Given numbers are 201,105,842,438

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

The LCM of 201,105,842,438 is 432413310.

Find LCM of 201,105,842,438 with Prime Factorization

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

2 x 3 x 67 x 35 x 421 x 73 = 432413310

Therefore, the lowest common multiple of 201,105,842,438 is 432413310.

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 105 x 842 x 438 = 7783439580

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

105 : 1, 3, 5, 7, 15, 21, 35, 105

842 : 1, 2, 421, 842

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 201,105,842,438, is 1.

Now, the common factors can be found like this.

201:3x 67

105:3x 5x 7

842:2x 421

438:2x 3x 73

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 7783439580/(1x18)

LCM = 7783439580/18

LCM = 432413310

Thus, we can understand that the LCM of 201,105,842,438 is 432413310.
