Given numbers are 431,402,486,249

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

The LCM of 431,402,486,249 is 1164840426.

Find LCM of 431,402,486,249 with Prime Factorization

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

2 x 3 x 431 x 67 x 81 x 83 = 1164840426

Therefore, the lowest common multiple of 431,402,486,249 is 1164840426.

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.

431 x 402 x 486 x 249 = 20967127668

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.

431 : 1, 431

402 : 1, 2, 3, 6, 67, 134, 201, 402

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

249 : 1, 3, 83, 249

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,402,486,249, is 1.

Now, the common factors can be found like this.

431:431

402:2x 3x 67

486:2x 3x 3x 3x 3x 3

249:3x 83

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 20967127668/(1x18)

LCM = 20967127668/18

LCM = 1164840426

Thus, we can understand that the LCM of 431,402,486,249 is 1164840426.
