Given numbers are 213,201,765,161

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

The LCM of 213,201,765,161 is 585895905.

Find LCM of 213,201,765,161 with Prime Factorization

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

3 x 71 x 67 x 255 x 161 = 585895905

Therefore, the lowest common multiple of 213,201,765,161 is 585895905.

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 201 x 765 x 161 = 5273063145

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

201 : 1, 3, 67, 201

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,201,765,161, is 1.

Now, the common factors can be found like this.

213:3x 71

201:3x 67

765:3x 3x 5x 17

161:7x 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 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 = 5273063145/(1x9)

LCM = 5273063145/9

LCM = 585895905

Thus, we can understand that the LCM of 213,201,765,161 is 585895905.
