Calculate the LCM of 161,638,575,800

Given numbers are 161,638,575,800

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

The LCM of 161,638,575,800 is 41087200.

Find LCM of 161,638,575,800 with Prime Factorization


2 161, 638, 575, 800
5 161, 319, 575, 400
5 161, 319, 115, 80
23 161, 319, 23, 16
7, 319, 1, 16

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

2 x 5 x 5 x 23 x 7 x 319 x 1 x 16 = 41087200

Therefore, the lowest common multiple of 161,638,575,800 is 41087200.

LCM Formula to Find Lowest Common Multiple of 161,638,575,800

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.

161 x 638 x 575 x 800 = 47250280000

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.

161 : 1, 7, 23, 161

638 : 1, 2, 11, 22, 29, 58, 319, 638

575 : 1, 5, 23, 25, 115, 575

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,638,575,800, is 1.

Now, the common factors can be found like this.

161:7x 23

638:2x 11x 29

575:5x 5x 23

800:2x 2x 2x 2x 2x 5x 5

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

2x 5x 5x 23 = 1150

Therefore, the value for common factors is 1150.

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 = 47250280000/(1x1150)

LCM = 47250280000/1150

LCM = 41087200

Thus, we can understand that the LCM of 161,638,575,800 is 41087200.
