LCM Formula to Find Lowest Common Multiple of 681,824,368,959,621

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.

681 x 824 x 368 x 959 x 621 = 122979394274688

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.

681 : 1, 3, 227, 681

824 : 1, 2, 4, 8, 103, 206, 412, 824

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

959 : 1, 7, 137, 959

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,824,368,959,621, is 1.

Now, the common factors can be found like this.

681:3x 227

824:2x 2x 2x 103

368:2x 2x 2x 2x 23

959:7x 137

621:3x 3x 3x 23

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 2x 3x 23 = 552

Therefore, the value for common factors is 552.

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 = 122979394274688/(1x552)

LCM = 122979394274688/552

LCM = 222788757744

Thus, we can understand that the LCM of 681,824,368,959,621 is 222788757744.
