Given numbers are 321,621,713,769

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

The LCM of 321,621,713,769 is 1584030033.

Find LCM of 321,621,713,769 with Prime Factorization

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

3 x 23 x 107 x 9 x 31 x 769 = 1584030033

Therefore, the lowest common multiple of 321,621,713,769 is 1584030033.

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.

321 x 621 x 713 x 769 = 109298072277

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.

321 : 1, 3, 107, 321

621 : 1, 3, 9, 23, 27, 69, 207, 621

713 : 1, 23, 31, 713

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,621,713,769, is 1.

Now, the common factors can be found like this.

321:3x 107

621:3x 3x 3x 23

713:23x 31

769:769

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

3x 23 = 69

Therefore, the value for common factors is 69.

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 = 109298072277/(1x69)

LCM = 109298072277/69

LCM = 1584030033

Thus, we can understand that the LCM of 321,621,713,769 is 1584030033.
