Given numbers are 681,309,996,821

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

The LCM of 681,309,996,821 is 19119017796.

Find LCM of 681,309,996,821 with Prime Factorization

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

3 x 227 x 103 x 332 x 821 = 19119017796

Therefore, the lowest common multiple of 681,309,996,821 is 19119017796.

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.

681 x 309 x 996 x 821 = 172071160164

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.

681 : 1, 3, 227, 681

309 : 1, 3, 103, 309

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,309,996,821, is 1.

Now, the common factors can be found like this.

681:3x 227

309:3x 103

996:2x 2x 3x 83

821:821

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 172071160164/(1x9)

LCM = 172071160164/9

LCM = 19119017796

Thus, we can understand that the LCM of 681,309,996,821 is 19119017796.
