Given numbers are 31,897,138

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

The LCM of 31,897,138 is 55614.

Find LCM of 31,897,138 with Prime Factorization

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

3 x 23 x 31 x 13 x 2 = 55614

Therefore, the lowest common multiple of 31,897,138 is 55614.

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.

31 x 897 x 138 = 3837366

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.

31 : 1, 31

897 : 1, 3, 13, 23, 39, 69, 299, 897

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 31,897,138, is 1.

Now, the common factors can be found like this.

31:31

897:3x 13x 23

138:2x 3x 23

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

3x 23 = 69

Therefore, the value for common factors is 69.

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 = 3837366/(1x69)

LCM = 3837366/69

LCM = 55614

Thus, we can understand that the LCM of 31,897,138 is 55614.

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

• LCM of 74, 160, 296
• LCM of 21, 385, 239
