Given numbers are 18,989,138

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

The LCM of 18,989,138 is 17802.

Find LCM of 18,989,138 with Prime Factorization

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

2 x 3 x 23 x 3 x 43 x 1 = 17802

Therefore, the lowest common multiple of 18,989,138 is 17802.

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.

18 x 989 x 138 = 2456676

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.

18 : 1, 2, 3, 6, 9, 18

989 : 1, 23, 43, 989

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 18,989,138, is 1.

Now, the common factors can be found like this.

18:2x 3x 3

989:23x 43

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.

2x 3x 23 = 138

Therefore, the value for common factors is 138.

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 = 2456676/(1x138)

LCM = 2456676/138

LCM = 17802

Thus, we can understand that the LCM of 18,989,138 is 17802.

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

• LCM of 99, 209, 361
• LCM of 12, 698, 306
