Given numbers are 397,666,671,213,547

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

The LCM of 397,666,671,213,547 is 6890217498054.

Find LCM of 397,666,671,213,547 with Prime Factorization

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

3 x 397 x 222 x 671 x 71 x 547 = 6890217498054

Therefore, the lowest common multiple of 397,666,671,213,547 is 6890217498054.

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.

397 x 666 x 671 x 213 x 547 = 20670652494162

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.

397 : 1, 397

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

671 : 1, 11, 61, 671

213 : 1, 3, 71, 213

547 : 1, 547

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,666,671,213,547, is 1.

Now, the common factors can be found like this.

397:397

666:2x 3x 3x 37

671:11x 61

213:3x 71

547:547

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

3 = 3

Therefore, the value for common factors is 3.

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 = 20670652494162/(1x3)

LCM = 20670652494162/3

LCM = 6890217498054

Thus, we can understand that the LCM of 397,666,671,213,547 is 6890217498054.
