LCM Formula to Find Lowest Common Multiple of 660,321,160,643,192

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 321 x 160 x 643 x 192 = 4184862105600

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

321 : 1, 3, 107, 321

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

643 : 1, 643

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,321,160,643,192, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

321:3x 107

160:2x 2x 2x 2x 2x 5

643:643

192:2x 2x 2x 2x 2x 2x 3

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 3x 5 = 5760

Therefore, the value for common factors is 5760.

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 = 4184862105600/(1x5760)

LCM = 4184862105600/5760

LCM = 726538560

Thus, we can understand that the LCM of 660,321,160,643,192 is 726538560.
