LCM Formula to Find Lowest Common Multiple of 432,621,807,721,810

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.

432 x 621 x 807 x 721 x 810 = 126435539291040

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.

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

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

807 : 1, 3, 269, 807

721 : 1, 7, 103, 721

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,621,807,721,810, is 1.

Now, the common factors can be found like this.

432:2x 2x 2x 2x 3x 3x 3

621:3x 3x 3x 23

807:3x 269

721:7x 103

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

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

2x 3x 3x 3x 3x 3x 3x 3 = 4374

Therefore, the value for common factors is 4374.

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 = 126435539291040/(1x4374)

LCM = 126435539291040/4374

LCM = 28906158960

Thus, we can understand that the LCM of 432,621,807,721,810 is 28906158960.
