Given numbers are 731,127,381

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

The LCM of 731,127,381 is 278511.

Find LCM of 731,127,381 with Prime Factorization

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

127 x 731 x 1 x 3 = 278511

Therefore, the lowest common multiple of 731,127,381 is 278511.

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.

731 x 127 x 381 = 35370897

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.

731 : 1, 17, 43, 731

127 : 1, 127

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,127,381, is 1.

Now, the common factors can be found like this.

731:17x 43

127:127

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.

127 = 127

Therefore, the value for common factors is 127.

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 = 35370897/(1x127)

LCM = 35370897/127

LCM = 278511

Thus, we can understand that the LCM of 731,127,381 is 278511.

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

• LCM of 709, 316, 626
