Calculate the LCM of 822,822,945

Given numbers are 822,822,945

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

The LCM of 822,822,945 is 258930.

Find LCM of 822,822,945 with Prime Factorization


2 822, 822, 945
3 411, 411, 945
137 137, 137, 315
1, 1, 315

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

2 x 3 x 137 x 1 x 1 x 315 = 258930

Therefore, the lowest common multiple of 822,822,945 is 258930.

LCM Formula to Find Lowest Common Multiple of 822,822,945

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.

822 x 822 x 945 = 638521380

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.

822 : 1, 2, 3, 6, 137, 274, 411, 822

822 : 1, 2, 3, 6, 137, 274, 411, 822

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,822,945, is 3.

Now, the common factors can be found like this.

822:2x 3x 137

822:2x 3x 137

945:3x 3x 3x 5x 7

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

2x 3x 137 = 822

Therefore, the value for common factors is 822.

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 = 638521380/(3x822)

LCM = 638521380/2466

LCM = 258930

Thus, we can understand that the LCM of 822,822,945 is 258930.
