Given numbers are 821,346,547,998

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

The LCM of 821,346,547,998 is 77536666898.

Find LCM of 821,346,547,998 with Prime Factorization

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

2 x 821 x 173 x 547 x 499 = 77536666898

Therefore, the lowest common multiple of 821,346,547,998 is 77536666898.

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.

821 x 346 x 547 x 998 = 155073333796

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.

821 : 1, 821

346 : 1, 2, 173, 346

547 : 1, 547

998 : 1, 2, 499, 998

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,346,547,998, is 1.

Now, the common factors can be found like this.

821:821

346:2x 173

547:547

998:2x 499

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 = 155073333796/(1x2)

LCM = 155073333796/2

LCM = 77536666898

Thus, we can understand that the LCM of 821,346,547,998 is 77536666898.
