Given numbers are 402,660,981,207,663

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

The LCM of 402,660,981,207,663 is 73499875020.

Find LCM of 402,660,981,207,663 with Prime Factorization

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

2 x 3 x 3 x 67 x 110 x 109 x 23 x 221 = 73499875020

Therefore, the lowest common multiple of 402,660,981,207,663 is 73499875020.

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.

402 x 660 x 981 x 207 x 663 = 35720939259720

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

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

981 : 1, 3, 9, 109, 327, 981

207 : 1, 3, 9, 23, 69, 207

663 : 1, 3, 13, 17, 39, 51, 221, 663

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,660,981,207,663, is 3.

Now, the common factors can be found like this.

402:2x 3x 67

660:2x 2x 3x 5x 11

981:3x 3x 109

207:3x 3x 23

663:3x 13x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3x 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 35720939259720/(3x162)

LCM = 35720939259720/486

LCM = 73499875020

Thus, we can understand that the LCM of 402,660,981,207,663 is 73499875020.
