Given numbers are 406,957,665,427

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

The LCM of 406,957,665,427 is 77641410.

Find LCM of 406,957,665,427 with Prime Factorization

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

7 x 29 x 2 x 33 x 95 x 61 = 77641410

Therefore, the lowest common multiple of 406,957,665,427 is 77641410.

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.

406 x 957 x 665 x 427 = 110328443610

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.

406 : 1, 2, 7, 14, 29, 58, 203, 406

957 : 1, 3, 11, 29, 33, 87, 319, 957

665 : 1, 5, 7, 19, 35, 95, 133, 665

427 : 1, 7, 61, 427

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,957,665,427, is 1.

Now, the common factors can be found like this.

406:2x 7x 29

957:3x 11x 29

665:5x 7x 19

427:7x 61

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

7x 7x 29 = 1421

Therefore, the value for common factors is 1421.

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 = 110328443610/(1x1421)

LCM = 110328443610/1421

LCM = 77641410

Thus, we can understand that the LCM of 406,957,665,427 is 77641410.
