Given numbers are 716,764,809,721

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

The LCM of 716,764,809,721 is 79768270484.

Find LCM of 716,764,809,721 with Prime Factorization

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

2 x 2 x 179 x 191 x 809 x 721 = 79768270484

Therefore, the lowest common multiple of 716,764,809,721 is 79768270484.

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.

716 x 764 x 809 x 721 = 319073081936

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.

716 : 1, 2, 4, 179, 358, 716

764 : 1, 2, 4, 191, 382, 764

809 : 1, 809

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,764,809,721, is 1.

Now, the common factors can be found like this.

716:2x 2x 179

764:2x 2x 191

809:809

721:7x 103

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 319073081936/(1x4)

LCM = 319073081936/4

LCM = 79768270484

Thus, we can understand that the LCM of 716,764,809,721 is 79768270484.
