Given numbers are 691,691,966,471

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

The LCM of 691,691,966,471 is 104798442.

Find LCM of 691,691,966,471 with Prime Factorization

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

3 x 691 x 1 x 1 x 322 x 157 = 104798442

Therefore, the lowest common multiple of 691,691,966,471 is 104798442.

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.

691 x 691 x 966 x 471 = 217247170266

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.

691 : 1, 691

691 : 1, 691

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

471 : 1, 3, 157, 471

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,691,966,471, is 1.

Now, the common factors can be found like this.

691:691

691:691

966:2x 3x 7x 23

471:3x 157

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

3x 691 = 2073

Therefore, the value for common factors is 2073.

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 = 217247170266/(1x2073)

LCM = 217247170266/2073

LCM = 104798442

Thus, we can understand that the LCM of 691,691,966,471 is 104798442.
