Given numbers are 221,182,242,266,381

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

The LCM of 221,182,242,266,381 is 2710093386.

Find LCM of 221,182,242,266,381 with Prime Factorization

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

2 x 7 x 13 x 17 x 1 x 121 x 19 x 381 = 2710093386

Therefore, the lowest common multiple of 221,182,242,266,381 is 2710093386.

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 182 x 242 x 266 x 381 = 986473992504

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

182 : 1, 2, 7, 13, 14, 26, 91, 182

242 : 1, 2, 11, 22, 121, 242

266 : 1, 2, 7, 14, 19, 38, 133, 266

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,182,242,266,381, is 1.

Now, the common factors can be found like this.

221:13x 17

182:2x 7x 13

242:2x 11x 11

266:2x 7x 19

381:3x 127

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

2x 2x 7x 13 = 364

Therefore, the value for common factors is 364.

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 = 986473992504/(1x364)

LCM = 986473992504/364

LCM = 2710093386

Thus, we can understand that the LCM of 221,182,242,266,381 is 2710093386.
