Given numbers are 428,93,681

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

The LCM of 428,93,681 is 9035508.

Find LCM of 428,93,681 with Prime Factorization

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

3 x 428 x 31 x 227 = 9035508

Therefore, the lowest common multiple of 428,93,681 is 9035508.

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.

428 x 93 x 681 = 27106524

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.

428 : 1, 2, 4, 107, 214, 428

93 : 1, 3, 31, 93

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,93,681, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

93:3x 31

681:3x 227

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 = 27106524/(1x3)

LCM = 27106524/3

LCM = 9035508

Thus, we can understand that the LCM of 428,93,681 is 9035508.

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

• LCM of 359, 88, 724
• LCM of 699, 16, 555
