Given numbers are 798,406,644,828

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

The LCM of 798,406,644,828 is 3193596.

Find LCM of 798,406,644,828 with Prime Factorization

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

2 x 2 x 3 x 7 x 23 x 19 x 29 x 1 x 3 = 3193596

Therefore, the lowest common multiple of 798,406,644,828 is 3193596.

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.

798 x 406 x 644 x 828 = 172760769216

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

406 : 1, 2, 7, 14, 29, 58, 203, 406

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,406,644,828, is 2.

Now, the common factors can be found like this.

798:2x 3x 7x 19

406:2x 7x 29

644:2x 2x 7x 23

828:2x 2x 3x 3x 23

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 3x 7x 7x 23 = 27048

Therefore, the value for common factors is 27048.

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 = 172760769216/(2x27048)

LCM = 172760769216/54096

LCM = 3193596

Thus, we can understand that the LCM of 798,406,644,828 is 3193596.
