Given numbers are 1989,5493

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

The LCM of 1989,5493 is 3641859.

Find LCM of 1989,5493 with Prime Factorization

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

3 x 663 x 1831 = 3641859

Therefore, the lowest common multiple of 1989,5493 is 3641859.

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.

1989 x 5493 = 10925577

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.

1989 : 1, 3, 9, 13, 17, 39, 51, 117, 153, 221, 663, 1989

5493 : 1, 3, 1831, 5493

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1989,5493, is 3.

Now, the common factors can be found like this.

1989:3x 3x 13x 17

5493:3x 1831

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 = 10925577/(3x1)

LCM = 10925577/3

LCM = 3641859

Thus, we can understand that the LCM of 1989,5493 is 3641859.

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

• LCM of 4186, 8408
• LCM of 2973, 1280
