Calculate the LCM of 811,978,800,797,100

Given numbers are 811,978,800,797,100

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

The LCM of 811,978,800,797,100 is 252858770400.

Find LCM of 811,978,800,797,100 with Prime Factorization


2 811, 978, 800, 797, 100
2 811, 489, 400, 797, 50
5 811, 489, 200, 797, 25
5 811, 489, 40, 797, 5
811, 489, 8, 797, 1

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

2 x 2 x 5 x 5 x 811 x 489 x 8 x 797 x 1 = 252858770400

Therefore, the lowest common multiple of 811,978,800,797,100 is 252858770400.

LCM Formula to Find Lowest Common Multiple of 811,978,800,797,100

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.

811 x 978 x 800 x 797 x 100 = 50571754080000

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.

811 : 1, 811

978 : 1, 2, 3, 6, 163, 326, 489, 978

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

797 : 1, 797

100 : 1, 2, 4, 5, 10, 20, 25, 50, 100

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,978,800,797,100, is 1.

Now, the common factors can be found like this.

811:811

978:2x 3x 163

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

797:797

100:2x 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 2x 2x 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 50571754080000/(1x200)

LCM = 50571754080000/200

LCM = 252858770400

Thus, we can understand that the LCM of 811,978,800,797,100 is 252858770400.
