LCM Formula to Find Lowest Common Multiple of 729,180,994,812

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.

729 x 180 x 994 x 812 = 105911336160

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.

729 : 1, 3, 9, 27, 81, 243, 729

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

994 : 1, 2, 7, 14, 71, 142, 497, 994

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,180,994,812, is 1.

Now, the common factors can be found like this.

729:3x 3x 3x 3x 3x 3

180:2x 2x 3x 3x 5

994:2x 7x 71

812:2x 2x 7x 29

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 3x 7 = 504

Therefore, the value for common factors is 504.

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 = 105911336160/(1x504)

LCM = 105911336160/504

LCM = 210141540

Thus, we can understand that the LCM of 729,180,994,812 is 210141540.
