Given numbers are 320,660,202,812

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

The LCM of 320,660,202,812 is 216511680.

Find LCM of 320,660,202,812 with Prime Factorization

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

2 x 2 x 5 x 16 x 33 x 101 x 203 = 216511680

Therefore, the lowest common multiple of 320,660,202,812 is 216511680.

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.

320 x 660 x 202 x 812 = 34641868800

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.

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

202 : 1, 2, 101, 202

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,660,202,812, is 2.

Now, the common factors can be found like this.

320:2x 2x 2x 2x 2x 2x 5

660:2x 2x 3x 5x 11

202:2x 101

812:2x 2x 7x 29

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

2x 2x 2x 2x 5 = 80

Therefore, the value for common factors is 80.

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 = 34641868800/(2x80)

LCM = 34641868800/160

LCM = 216511680

Thus, we can understand that the LCM of 320,660,202,812 is 216511680.
