Given numbers are 621,521,201,201

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

The LCM of 621,521,201,201 is 21677247.

Find LCM of 621,521,201,201 with Prime Factorization

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

3 x 67 x 207 x 521 x 1 x 1 = 21677247

Therefore, the lowest common multiple of 621,521,201,201 is 21677247.

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.

621 x 521 x 201 x 201 = 13071379941

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

521 : 1, 521

201 : 1, 3, 67, 201

201 : 1, 3, 67, 201

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,521,201,201, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

521:521

201:3x 67

201:3x 67

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 67 = 603

Therefore, the value for common factors is 603.

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 = 13071379941/(1x603)

LCM = 13071379941/603

LCM = 21677247

Thus, we can understand that the LCM of 621,521,201,201 is 21677247.
