Calculate the LCM of 201,990,110,689

Given numbers are 201,990,110,689

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

The LCM of 201,990,110,689 is 45701370.

Find LCM of 201,990,110,689 with Prime Factorization


2 201, 990, 110, 689
3 201, 495, 55, 689
5 67, 165, 55, 689
11 67, 33, 11, 689
67, 3, 1, 689

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

2 x 3 x 5 x 11 x 67 x 3 x 1 x 689 = 45701370

Therefore, the lowest common multiple of 201,990,110,689 is 45701370.

LCM Formula to Find Lowest Common Multiple of 201,990,110,689

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.

201 x 990 x 110 x 689 = 15081452100

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.

201 : 1, 3, 67, 201

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

110 : 1, 2, 5, 10, 11, 22, 55, 110

689 : 1, 13, 53, 689

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 201,990,110,689, is 1.

Now, the common factors can be found like this.

201:3x 67

990:2x 3x 3x 5x 11

110:2x 5x 11

689:13x 53

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 5x 11 = 330

Therefore, the value for common factors is 330.

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 = 15081452100/(1x330)

LCM = 15081452100/330

LCM = 45701370

Thus, we can understand that the LCM of 201,990,110,689 is 45701370.
