Calculate the LCM of 823,425,442,172

Given numbers are 823,425,442,172

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

The LCM of 823,425,442,172 is 782096900.

Find LCM of 823,425,442,172 with Prime Factorization


2 823, 425, 442, 172
17 823, 425, 221, 86
823, 25, 13, 86

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

2 x 17 x 823 x 25 x 13 x 86 = 782096900

Therefore, the lowest common multiple of 823,425,442,172 is 782096900.

LCM Formula to Find Lowest Common Multiple of 823,425,442,172

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 425 x 442 x 172 = 26591294600

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

425 : 1, 5, 17, 25, 85, 425

442 : 1, 2, 13, 17, 26, 34, 221, 442

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 823,425,442,172, is 1.

Now, the common factors can be found like this.

823:823

425:5x 5x 17

442:2x 13x 17

172:2x 2x 43

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 26591294600/(1x34)

LCM = 26591294600/34

LCM = 782096900

Thus, we can understand that the LCM of 823,425,442,172 is 782096900.
