LCM Formula to Find Lowest Common Multiple of 821,728,919,666

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.

821 x 728 x 919 x 666 = 365817331152

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.

821 : 1, 821

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

919 : 1, 919

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,728,919,666, is 1.

Now, the common factors can be found like this.

821:821

728:2x 2x 2x 7x 13

919:919

666:2x 3x 3x 37

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 = 365817331152/(1x2)

LCM = 365817331152/2

LCM = 182908665576

Thus, we can understand that the LCM of 821,728,919,666 is 182908665576.
