Given numbers are 8938,1390

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

The LCM of 8938,1390 is 6211910.

Find LCM of 8938,1390 with Prime Factorization

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

2 x 4469 x 695 = 6211910

Therefore, the lowest common multiple of 8938,1390 is 6211910.

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.

8938 x 1390 = 12423820

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.

8938 : 1, 2, 41, 82, 109, 218, 4469, 8938

1390 : 1, 2, 5, 10, 139, 278, 695, 1390

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8938,1390, is 2.

Now, the common factors can be found like this.

8938:2x 41x 109

1390:2x 5x 139

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 = 12423820/(2x1)

LCM = 12423820/2

LCM = 6211910

Thus, we can understand that the LCM of 8938,1390 is 6211910.

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

• LCM of 2609, 9291
• LCM of 6524, 2700
