LCM Formula to Find Lowest Common Multiple of 660,308,141,685

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.

660 x 308 x 141 x 685 = 19633798800

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

141 : 1, 3, 47, 141

685 : 1, 5, 137, 685

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,308,141,685, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

308:2x 2x 7x 11

141:3x 47

685:5x 137

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 5x 11 = 660

Therefore, the value for common factors is 660.

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 = 19633798800/(1x660)

LCM = 19633798800/660

LCM = 29748180

Thus, we can understand that the LCM of 660,308,141,685 is 29748180.
