Given numbers are 420,687,558,503

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

The LCM of 420,687,558,503 is 4499204220.

Find LCM of 420,687,558,503 with Prime Factorization

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

2 x 3 x 70 x 229 x 93 x 503 = 4499204220

Therefore, the lowest common multiple of 420,687,558,503 is 4499204220.

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 687 x 558 x 503 = 80985675960

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

687 : 1, 3, 229, 687

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

503 : 1, 503

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,687,558,503, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

687:3x 229

558:2x 3x 3x 31

503:503

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 = 80985675960/(1x18)

LCM = 80985675960/18

LCM = 4499204220

Thus, we can understand that the LCM of 420,687,558,503 is 4499204220.
