Given numbers are 681,667,227,691

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

The LCM of 681,667,227,691 is 313870857.

Find LCM of 681,667,227,691 with Prime Factorization

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

227 x 3 x 667 x 1 x 691 = 313870857

Therefore, the lowest common multiple of 681,667,227,691 is 313870857.

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 667 x 227 x 691 = 71248684539

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

667 : 1, 23, 29, 667

227 : 1, 227

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,667,227,691, is 1.

Now, the common factors can be found like this.

681:3x 227

667:23x 29

227:227

691:691

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

227 = 227

Therefore, the value for common factors is 227.

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 = 71248684539/(1x227)

LCM = 71248684539/227

LCM = 313870857

Thus, we can understand that the LCM of 681,667,227,691 is 313870857.
