Calculate the LCM of 823,686,544,835

Given numbers are 823,686,544,835

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

The LCM of 823,686,544,835 is 128226955360.

Find LCM of 823,686,544,835 with Prime Factorization


2 823, 686, 544, 835
823, 343, 272, 835

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

2 x 823 x 343 x 272 x 835 = 128226955360

Therefore, the lowest common multiple of 823,686,544,835 is 128226955360.

LCM Formula to Find Lowest Common Multiple of 823,686,544,835

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 686 x 544 x 835 = 256453910720

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544

835 : 1, 5, 167, 835

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,686,544,835, is 1.

Now, the common factors can be found like this.

823:823

686:2x 7x 7x 7

544:2x 2x 2x 2x 2x 17

835:5x 167

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

2 = 2

Therefore, the value for common factors is 2.

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 = 256453910720/(1x2)

LCM = 256453910720/2

LCM = 128226955360

Thus, we can understand that the LCM of 823,686,544,835 is 128226955360.
