Given numbers are 394,7638

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

The LCM of 394,7638 is 1504686.

Find LCM of 394,7638 with Prime Factorization

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

2 x 197 x 3819 = 1504686

Therefore, the lowest common multiple of 394,7638 is 1504686.

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.

394 x 7638 = 3009372

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.

394 : 1, 2, 197, 394

7638 : 1, 2, 3, 6, 19, 38, 57, 67, 114, 134, 201, 402, 1273, 2546, 3819, 7638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,7638, is 2.

Now, the common factors can be found like this.

394:2x 197

7638:2x 3x 19x 67

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

= 1

Therefore, the value for common factors is 1.

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 = 3009372/(2x1)

LCM = 3009372/2

LCM = 1504686

Thus, we can understand that the LCM of 394,7638 is 1504686.

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

• LCM of 577, 5411
• LCM of 836, 6411
