Given numbers are 431,679,161,920

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

The LCM of 431,679,161,920 is 269237080.

Find LCM of 431,679,161,920 with Prime Factorization

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

7 x 23 x 431 x 97 x 1 x 40 = 269237080

Therefore, the lowest common multiple of 431,679,161,920 is 269237080.

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.

431 x 679 x 161 x 920 = 43347169880

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.

431 : 1, 431

679 : 1, 7, 97, 679

161 : 1, 7, 23, 161

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,679,161,920, is 1.

Now, the common factors can be found like this.

431:431

679:7x 97

161:7x 23

920:2x 2x 2x 5x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 43347169880/(1x161)

LCM = 43347169880/161

LCM = 269237080

Thus, we can understand that the LCM of 431,679,161,920 is 269237080.
