Given numbers are 791,709,721,728

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

The LCM of 791,709,721,728 is 6007493128.

Find LCM of 791,709,721,728 with Prime Factorization

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

7 x 113 x 709 x 103 x 104 = 6007493128

Therefore, the lowest common multiple of 791,709,721,728 is 6007493128.

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.

791 x 709 x 721 x 728 = 294367163272

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.

791 : 1, 7, 113, 791

709 : 1, 709

721 : 1, 7, 103, 721

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,709,721,728, is 1.

Now, the common factors can be found like this.

791:7x 113

709:709

721:7x 103

728:2x 2x 2x 7x 13

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 294367163272/(1x49)

LCM = 294367163272/49

LCM = 6007493128

Thus, we can understand that the LCM of 791,709,721,728 is 6007493128.
