LCM Formula to Find Lowest Common Multiple of 189,666,999,435

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.

189 x 666 x 999 x 435 = 54700434810

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

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

999 : 1, 3, 9, 27, 37, 111, 333, 999

435 : 1, 3, 5, 15, 29, 87, 145, 435

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,666,999,435, is 3.

Now, the common factors can be found like this.

189:3x 3x 3x 7

666:2x 3x 3x 37

999:3x 3x 3x 37

435:3x 5x 29

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

3x 3x 3x 3x 3x 37 = 8991

Therefore, the value for common factors is 8991.

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 = 54700434810/(3x8991)

LCM = 54700434810/26973

LCM = 2027970

Thus, we can understand that the LCM of 189,666,999,435 is 2027970.
