Given numbers are 771,81,386

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

The LCM of 771,81,386 is 8035362.

Find LCM of 771,81,386 with Prime Factorization

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

3 x 257 x 27 x 386 = 8035362

Therefore, the lowest common multiple of 771,81,386 is 8035362.

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.

771 x 81 x 386 = 24106086

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.

771 : 1, 3, 257, 771

81 : 1, 3, 9, 27, 81

386 : 1, 2, 193, 386

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,81,386, is 1.

Now, the common factors can be found like this.

771:3x 257

81:3x 3x 3x 3

386:2x 193

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

3 = 3

Therefore, the value for common factors is 3.

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 = 24106086/(1x3)

LCM = 24106086/3

LCM = 8035362

Thus, we can understand that the LCM of 771,81,386 is 8035362.

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

• LCM of 442, 17, 618
• LCM of 832, 19, 632
