Given numbers are 203,23,391,403

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

The LCM of 203,23,391,403 is 31987319.

Find LCM of 203,23,391,403 with Prime Factorization

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

23 x 203 x 1 x 17 x 403 = 31987319

Therefore, the lowest common multiple of 203,23,391,403 is 31987319.

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.

203 x 23 x 391 x 403 = 735708337

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.

203 : 1, 7, 29, 203

23 : 1, 23

391 : 1, 17, 23, 391

403 : 1, 13, 31, 403

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,23,391,403, is 1.

Now, the common factors can be found like this.

203:7x 29

23:23

391:17x 23

403:13x 31

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

23 = 23

Therefore, the value for common factors is 23.

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 = 735708337/(1x23)

LCM = 735708337/23

LCM = 31987319

Thus, we can understand that the LCM of 203,23,391,403 is 31987319.

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

• LCM of 719, 68, 904, 121
