Given numbers are 397,667,249,487,639

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

The LCM of 397,667,249,487,639 is 6839498402181.

Find LCM of 397,667,249,487,639 with Prime Factorization

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

3 x 397 x 667 x 83 x 487 x 213 = 6839498402181

Therefore, the lowest common multiple of 397,667,249,487,639 is 6839498402181.

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 667 x 249 x 487 x 639 = 20518495206543

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

667 : 1, 23, 29, 667

249 : 1, 3, 83, 249

487 : 1, 487

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,667,249,487,639, is 1.

Now, the common factors can be found like this.

397:397

667:23x 29

249:3x 83

487:487

639:3x 3x 71

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 = 20518495206543/(1x3)

LCM = 20518495206543/3

LCM = 6839498402181

Thus, we can understand that the LCM of 397,667,249,487,639 is 6839498402181.
