Given numbers are 420,586,854,587

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

The LCM of 420,586,854,587 is 4406409420.

Find LCM of 420,586,854,587 with Prime Factorization

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

2 x 7 x 30 x 293 x 61 x 587 = 4406409420

Therefore, the lowest common multiple of 420,586,854,587 is 4406409420.

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 586 x 854 x 587 = 123379463760

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

586 : 1, 2, 293, 586

854 : 1, 2, 7, 14, 61, 122, 427, 854

587 : 1, 587

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,586,854,587, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

586:2x 293

854:2x 7x 61

587:587

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 123379463760/(1x28)

LCM = 123379463760/28

LCM = 4406409420

Thus, we can understand that the LCM of 420,586,854,587 is 4406409420.
