LCM Formula to Find Lowest Common Multiple of 680,242,132,636,128

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.

680 x 242 x 132 x 636 x 128 = 1768338063360

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

242 : 1, 2, 11, 22, 121, 242

132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

128 : 1, 2, 4, 8, 16, 32, 64, 128

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,242,132,636,128, is 2.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

242:2x 11x 11

132:2x 2x 3x 11

636:2x 2x 3x 53

128:2x 2x 2x 2x 2x 2x 2

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 2x 2x 3x 11 = 4224

Therefore, the value for common factors is 4224.

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 = 1768338063360/(2x4224)

LCM = 1768338063360/8448

LCM = 209320320

Thus, we can understand that the LCM of 680,242,132,636,128 is 209320320.
