Given numbers are 1698,9980

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

The LCM of 1698,9980 is 8473020.

Find LCM of 1698,9980 with Prime Factorization

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

2 x 849 x 4990 = 8473020

Therefore, the lowest common multiple of 1698,9980 is 8473020.

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.

1698 x 9980 = 16946040

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.

1698 : 1, 2, 3, 6, 283, 566, 849, 1698

9980 : 1, 2, 4, 5, 10, 20, 499, 998, 1996, 2495, 4990, 9980

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1698,9980, is 2.

Now, the common factors can be found like this.

1698:2x 3x 283

9980:2x 2x 5x 499

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 = 16946040/(2x1)

LCM = 16946040/2

LCM = 8473020

Thus, we can understand that the LCM of 1698,9980 is 8473020.

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

• LCM of 2741, 1851
• LCM of 3790, 3256
