Given numbers are 621,791,368,115

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

The LCM of 621,791,368,115 is 39296880.

Find LCM of 621,791,368,115 with Prime Factorization

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

23 x 27 x 791 x 16 x 5 = 39296880

Therefore, the lowest common multiple of 621,791,368,115 is 39296880.

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.

621 x 791 x 368 x 115 = 20788049520

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.

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

791 : 1, 7, 113, 791

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,791,368,115, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

791:7x 113

368:2x 2x 2x 2x 23

115:5x 23

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 20788049520/(1x529)

LCM = 20788049520/529

LCM = 39296880

Thus, we can understand that the LCM of 621,791,368,115 is 39296880.
