Calculate the LCM of 823,250,256,647,642

Given numbers are 823,250,256,647,642

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

The LCM of 823,250,256,647,642 is 5469644832000.

Find LCM of 823,250,256,647,642 with Prime Factorization


2 823, 250, 256, 647, 642
823, 125, 128, 647, 321

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

2 x 823 x 125 x 128 x 647 x 321 = 5469644832000

Therefore, the lowest common multiple of 823,250,256,647,642 is 5469644832000.

LCM Formula to Find Lowest Common Multiple of 823,250,256,647,642

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.

823 x 250 x 256 x 647 x 642 = 21878579328000

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.

823 : 1, 823

250 : 1, 2, 5, 10, 25, 50, 125, 250

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

647 : 1, 647

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,250,256,647,642, is 1.

Now, the common factors can be found like this.

823:823

250:2x 5x 5x 5

256:2x 2x 2x 2x 2x 2x 2x 2

647:647

642:2x 3x 107

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 21878579328000/(1x4)

LCM = 21878579328000/4

LCM = 5469644832000

Thus, we can understand that the LCM of 823,250,256,647,642 is 5469644832000.
