LCM Formula to Find Lowest Common Multiple of 721,830,689,396

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.

721 x 830 x 689 x 396 = 163278034920

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.

721 : 1, 7, 103, 721

830 : 1, 2, 5, 10, 83, 166, 415, 830

689 : 1, 13, 53, 689

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,830,689,396, is 1.

Now, the common factors can be found like this.

721:7x 103

830:2x 5x 83

689:13x 53

396:2x 2x 3x 3x 11

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

2 = 2

Therefore, the value for common factors is 2.

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 = 163278034920/(1x2)

LCM = 163278034920/2

LCM = 81639017460

Thus, we can understand that the LCM of 721,830,689,396 is 81639017460.
