The LCM of 825,243,341,921 is 635973525.

Find LCM of 825,243,341,921 with Prime Factorization


3 825, 243, 341, 921
11 275, 81, 341, 307
25, 81, 31, 307

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

3 x 11 x 25 x 81 x 31 x 307 = 635973525

Therefore, the lowest common multiple of 825,243,341,921 is 635973525.

LCM Formula to Find Lowest Common Multiple of 825,243,341,921

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.

825 x 243 x 341 x 921 = 62961378975

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.

825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

243 : 1, 3, 9, 27, 81, 243

341 : 1, 11, 31, 341

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 825,243,341,921, is 1.

Now, the common factors can be found like this.

825:3x 5x 5x 11

243:3x 3x 3x 3x 3

341:11x 31

921:3x 307

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

3x 3x 11 = 99

Therefore, the value for common factors is 99.

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 = 62961378975/(1x99)

LCM = 62961378975/99

LCM = 635973525

Thus, we can understand that the LCM of 825,243,341,921 is 635973525.
