Given numbers are 420,481,538,827,863

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

The LCM of 420,481,538,827,863 is 38784924649380.

Find LCM of 420,481,538,827,863 with Prime Factorization

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

2 x 210 x 481 x 269 x 827 x 863 = 38784924649380

Therefore, the lowest common multiple of 420,481,538,827,863 is 38784924649380.

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.

420 x 481 x 538 x 827 x 863 = 77569849298760

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

481 : 1, 13, 37, 481

538 : 1, 2, 269, 538

827 : 1, 827

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,481,538,827,863, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

481:13x 37

538:2x 269

827:827

863:863

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 = 77569849298760/(1x2)

LCM = 77569849298760/2

LCM = 38784924649380

Thus, we can understand that the LCM of 420,481,538,827,863 is 38784924649380.
