LCM Formula to Find Lowest Common Multiple of 198,561,112,992

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.

198 x 561 x 112 x 992 = 12341210112

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

561 : 1, 3, 11, 17, 33, 51, 187, 561

112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,561,112,992, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

561:3x 11x 17

112:2x 2x 2x 2x 7

992:2x 2x 2x 2x 2x 31

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 2x 2x 3x 11 = 1056

Therefore, the value for common factors is 1056.

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 = 12341210112/(1x1056)

LCM = 12341210112/1056

LCM = 11686752

Thus, we can understand that the LCM of 198,561,112,992 is 11686752.
