Given numbers are 221,491,982,913

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

The LCM of 221,491,982,913 is 198141086.

Find LCM of 221,491,982,913 with Prime Factorization

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

491 x 221 x 1 x 2 x 913 = 198141086

Therefore, the lowest common multiple of 221,491,982,913 is 198141086.

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.

221 x 491 x 982 x 913 = 97287273226

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.

221 : 1, 13, 17, 221

491 : 1, 491

982 : 1, 2, 491, 982

913 : 1, 11, 83, 913

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,491,982,913, is 1.

Now, the common factors can be found like this.

221:13x 17

491:491

982:2x 491

913:11x 83

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

491 = 491

Therefore, the value for common factors is 491.

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 = 97287273226/(1x491)

LCM = 97287273226/491

LCM = 198141086

Thus, we can understand that the LCM of 221,491,982,913 is 198141086.
