Given numbers are 213,207,201,644

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

The LCM of 213,207,201,644 is 27571572.

Find LCM of 213,207,201,644 with Prime Factorization

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

3 x 23 x 71 x 3 x 67 x 28 = 27571572

Therefore, the lowest common multiple of 213,207,201,644 is 27571572.

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.

213 x 207 x 201 x 644 = 5707315404

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.

213 : 1, 3, 71, 213

207 : 1, 3, 9, 23, 69, 207

201 : 1, 3, 67, 201

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,207,201,644, is 1.

Now, the common factors can be found like this.

213:3x 71

207:3x 3x 23

201:3x 67

644:2x 2x 7x 23

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

3x 3x 23 = 207

Therefore, the value for common factors is 207.

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 = 5707315404/(1x207)

LCM = 5707315404/207

LCM = 27571572

Thus, we can understand that the LCM of 213,207,201,644 is 27571572.
