Calculate the LCM of 990,663,197,676

Given numbers are 990,663,197,676

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

The LCM of 990,663,197,676 is 1120642380.

Find LCM of 990,663,197,676 with Prime Factorization


2 990, 663, 197, 676
3 495, 663, 197, 338
13 165, 221, 197, 338
165, 17, 197, 26

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

2 x 3 x 13 x 165 x 17 x 197 x 26 = 1120642380

Therefore, the lowest common multiple of 990,663,197,676 is 1120642380.

LCM Formula to Find Lowest Common Multiple of 990,663,197,676

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.

990 x 663 x 197 x 676 = 87410105640

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

663 : 1, 3, 13, 17, 39, 51, 221, 663

197 : 1, 197

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,663,197,676, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

663:3x 13x 17

197:197

676:2x 2x 13x 13

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 13 = 78

Therefore, the value for common factors is 78.

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 = 87410105640/(1x78)

LCM = 87410105640/78

LCM = 1120642380

Thus, we can understand that the LCM of 990,663,197,676 is 1120642380.
