Given numbers are 670,38,412

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

The LCM of 670,38,412 is 2622380.

Find LCM of 670,38,412 with Prime Factorization

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

2 x 335 x 19 x 206 = 2622380

Therefore, the lowest common multiple of 670,38,412 is 2622380.

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.

670 x 38 x 412 = 10489520

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

38 : 1, 2, 19, 38

412 : 1, 2, 4, 103, 206, 412

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,38,412, is 2.

Now, the common factors can be found like this.

670:2x 5x 67

38:2x 19

412:2x 2x 103

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 = 10489520/(2x2)

LCM = 10489520/4

LCM = 2622380

Thus, we can understand that the LCM of 670,38,412 is 2622380.

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

• LCM of 191, 92, 127
• LCM of 472, 38, 912
