LCM Formula to Find Lowest Common Multiple of 984,385,388,693

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.

984 x 385 x 388 x 693 = 101864014560

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.

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

385 : 1, 5, 7, 11, 35, 55, 77, 385

388 : 1, 2, 4, 97, 194, 388

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,385,388,693, is 1.

Now, the common factors can be found like this.

984:2x 2x 2x 3x 41

385:5x 7x 11

388:2x 2x 97

693:3x 3x 7x 11

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 3x 7x 11 = 924

Therefore, the value for common factors is 924.

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 = 101864014560/(1x924)

LCM = 101864014560/924

LCM = 110242440

Thus, we can understand that the LCM of 984,385,388,693 is 110242440.
