Given numbers are 777,18,489

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

The LCM of 777,18,489 is 759906.

Find LCM of 777,18,489 with Prime Factorization

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

3 x 259 x 6 x 163 = 759906

Therefore, the lowest common multiple of 777,18,489 is 759906.

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.

777 x 18 x 489 = 6839154

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.

777 : 1, 3, 7, 21, 37, 111, 259, 777

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

489 : 1, 3, 163, 489

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,18,489, is 3.

Now, the common factors can be found like this.

777:3x 7x 37

18:2x 3x 3

489:3x 163

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

3 = 3

Therefore, the value for common factors is 3.

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 = 6839154/(3x3)

LCM = 6839154/9

LCM = 759906

Thus, we can understand that the LCM of 777,18,489 is 759906.

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

• LCM of 437, 15, 956
• LCM of 384, 52, 287
