Given numbers are 411,82,428

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

The LCM of 411,82,428 is 7212228.

Find LCM of 411,82,428 with Prime Factorization

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

2 x 411 x 41 x 214 = 7212228

Therefore, the lowest common multiple of 411,82,428 is 7212228.

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.

411 x 82 x 428 = 14424456

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.

411 : 1, 3, 137, 411

82 : 1, 2, 41, 82

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,82,428, is 1.

Now, the common factors can be found like this.

411:3x 137

82:2x 41

428:2x 2x 107

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

2 = 2

Therefore, the value for common factors is 2.

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 = 14424456/(1x2)

LCM = 14424456/2

LCM = 7212228

Thus, we can understand that the LCM of 411,82,428 is 7212228.

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

• LCM of 945, 46, 750
• LCM of 785, 69, 719
