Calculate the LCM of 191,201,156,861

Given numbers are 191,201,156,861

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

The LCM of 191,201,156,861 is 572947284.

Find LCM of 191,201,156,861 with Prime Factorization


3 191, 201, 156, 861
191, 67, 52, 287

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

3 x 191 x 67 x 52 x 287 = 572947284

Therefore, the lowest common multiple of 191,201,156,861 is 572947284.

LCM Formula to Find Lowest Common Multiple of 191,201,156,861

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.

191 x 201 x 156 x 861 = 5156525556

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.

191 : 1, 191

201 : 1, 3, 67, 201

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,201,156,861, is 1.

Now, the common factors can be found like this.

191:191

201:3x 67

156:2x 2x 3x 13

861:3x 7x 41

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 5156525556/(1x9)

LCM = 5156525556/9

LCM = 572947284

Thus, we can understand that the LCM of 191,201,156,861 is 572947284.
