Given numbers are 197,422,463,646

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

The LCM of 197,422,463,646 is 12432606566.

Find LCM of 197,422,463,646 with Prime Factorization

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

2 x 197 x 211 x 463 x 323 = 12432606566

Therefore, the lowest common multiple of 197,422,463,646 is 12432606566.

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.

197 x 422 x 463 x 646 = 24865213132

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.

197 : 1, 197

422 : 1, 2, 211, 422

463 : 1, 463

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,422,463,646, is 1.

Now, the common factors can be found like this.

197:197

422:2x 211

463:463

646:2x 17x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 24865213132/(1x2)

LCM = 24865213132/2

LCM = 12432606566

Thus, we can understand that the LCM of 197,422,463,646 is 12432606566.

Here are some samples of LCM of two or more Numbers calculations.
