Given numbers are 201,728,805,665

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

The LCM of 201,728,805,665 is 319726680.

Find LCM of 201,728,805,665 with Prime Factorization

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

5 x 7 x 201 x 104 x 23 x 19 = 319726680

Therefore, the lowest common multiple of 201,728,805,665 is 319726680.

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 728 x 805 x 665 = 78333036600

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

805 : 1, 5, 7, 23, 35, 115, 161, 805

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 201,728,805,665, is 1.

Now, the common factors can be found like this.

201:3x 67

728:2x 2x 2x 7x 13

805:5x 7x 23

665:5x 7x 19

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

5x 7x 7 = 245

Therefore, the value for common factors is 245.

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 = 78333036600/(1x245)

LCM = 78333036600/245

LCM = 319726680

Thus, we can understand that the LCM of 201,728,805,665 is 319726680.
