Given numbers are 223,471,221,511,681

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

The LCM of 223,471,221,511,681 is 2692556351121.

Find LCM of 223,471,221,511,681 with Prime Factorization

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

3 x 223 x 157 x 221 x 511 x 227 = 2692556351121

Therefore, the lowest common multiple of 223,471,221,511,681 is 2692556351121.

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.

223 x 471 x 221 x 511 x 681 = 8077669053363

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.

223 : 1, 223

471 : 1, 3, 157, 471

221 : 1, 13, 17, 221

511 : 1, 7, 73, 511

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,471,221,511,681, is 1.

Now, the common factors can be found like this.

223:223

471:3x 157

221:13x 17

511:7x 73

681:3x 227

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

3 = 3

Therefore, the value for common factors is 3.

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 = 8077669053363/(1x3)

LCM = 8077669053363/3

LCM = 2692556351121

Thus, we can understand that the LCM of 223,471,221,511,681 is 2692556351121.
