Given numbers are 728,810,717,670

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

The LCM of 728,810,717,670 is 4721272920.

Find LCM of 728,810,717,670 with Prime Factorization

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

2 x 3 x 5 x 364 x 27 x 239 x 67 = 4721272920

Therefore, the lowest common multiple of 728,810,717,670 is 4721272920.

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.

728 x 810 x 717 x 670 = 283276375200

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.

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

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

717 : 1, 3, 239, 717

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,810,717,670, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

810:2x 3x 3x 3x 3x 5

717:3x 239

670:2x 5x 67

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

2x 2x 3x 5 = 60

Therefore, the value for common factors is 60.

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 = 283276375200/(1x60)

LCM = 283276375200/60

LCM = 4721272920

Thus, we can understand that the LCM of 728,810,717,670 is 4721272920.
