Given numbers are 320,975,721,166

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

The LCM of 320,975,721,166 is 3734203200.

Find LCM of 320,975,721,166 with Prime Factorization

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

2 x 5 x 32 x 195 x 721 x 83 = 3734203200

Therefore, the lowest common multiple of 320,975,721,166 is 3734203200.

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 975 x 721 x 166 = 37342032000

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

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

721 : 1, 7, 103, 721

166 : 1, 2, 83, 166

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,975,721,166, is 1.

Now, the common factors can be found like this.

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

975:3x 5x 5x 13

721:7x 103

166:2x 83

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 37342032000/(1x10)

LCM = 37342032000/10

LCM = 3734203200

Thus, we can understand that the LCM of 320,975,721,166 is 3734203200.
