Given numbers are 281,491,491

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

The LCM of 281,491,491 is 137971.

Find LCM of 281,491,491 with Prime Factorization

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

491 x 281 x 1 x 1 = 137971

Therefore, the lowest common multiple of 281,491,491 is 137971.

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.

281 x 491 x 491 = 67743761

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.

281 : 1, 281

491 : 1, 491

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,491,491, is 1.

Now, the common factors can be found like this.

281:281

491:491

491:491

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 = 67743761/(1x491)

LCM = 67743761/491

LCM = 137971

Thus, we can understand that the LCM of 281,491,491 is 137971.

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

• LCM of 833, 831, 646
