Given numbers are 660,154,398,111,246

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 660,154,398,111,246 is 1394699460.

Find LCM of 660,154,398,111,246 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 11 x 10 x 7 x 199 x 37 x 41 = 1394699460

Therefore, the lowest common multiple of 660,154,398,111,246 is 1394699460.

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 154 x 398 x 111 x 246 = 1104601972320

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

154 : 1, 2, 7, 11, 14, 22, 77, 154

398 : 1, 2, 199, 398

111 : 1, 3, 37, 111

246 : 1, 2, 3, 6, 41, 82, 123, 246

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,154,398,111,246, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

154:2x 7x 11

398:2x 199

111:3x 37

246:2x 3x 41

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 3x 3x 11 = 792

Therefore, the value for common factors is 792.

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 = 1104601972320/(1x792)

LCM = 1104601972320/792

LCM = 1394699460

Thus, we can understand that the LCM of 660,154,398,111,246 is 1394699460.
