Given numbers are 727,621,171,791

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

The LCM of 727,621,171,791 is 6785097543.

Find LCM of 727,621,171,791 with Prime Factorization

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

3 x 3 x 727 x 69 x 19 x 791 = 6785097543

Therefore, the lowest common multiple of 727,621,171,791 is 6785097543.

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.

727 x 621 x 171 x 791 = 61065877887

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.

727 : 1, 727

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

171 : 1, 3, 9, 19, 57, 171

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,621,171,791, is 1.

Now, the common factors can be found like this.

727:727

621:3x 3x 3x 23

171:3x 3x 19

791:7x 113

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 61065877887/(1x9)

LCM = 61065877887/9

LCM = 6785097543

Thus, we can understand that the LCM of 727,621,171,791 is 6785097543.
