Given numbers are 221,169,391

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

The LCM of 221,169,391 is 66079.

Find LCM of 221,169,391 with Prime Factorization

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

13 x 17 x 1 x 13 x 23 = 66079

Therefore, the lowest common multiple of 221,169,391 is 66079.

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 169 x 391 = 14603459

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

169 : 1, 13, 169

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,169,391, is 1.

Now, the common factors can be found like this.

221:13x 17

169:13x 13

391:17x 23

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

13x 17 = 221

Therefore, the value for common factors is 221.

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 = 14603459/(1x221)

LCM = 14603459/221

LCM = 66079

Thus, we can understand that the LCM of 221,169,391 is 66079.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 855, 733, 577
• LCM of 847, 177, 570
