The LCM of 822,993,789,688 is 24615802704.

Find LCM of 822,993,789,688 with Prime Factorization


2 822, 993, 789, 688
3 411, 993, 789, 344
137, 331, 263, 344

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

2 x 3 x 137 x 331 x 263 x 344 = 24615802704

Therefore, the lowest common multiple of 822,993,789,688 is 24615802704.

LCM Formula to Find Lowest Common Multiple of 822,993,789,688

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 993 x 789 x 688 = 443084448672

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

993 : 1, 3, 331, 993

789 : 1, 3, 263, 789

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,993,789,688, is 1.

Now, the common factors can be found like this.

822:2x 3x 137

993:3x 331

789:3x 263

688:2x 2x 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 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 443084448672/(1x18)

LCM = 443084448672/18

LCM = 24615802704

Thus, we can understand that the LCM of 822,993,789,688 is 24615802704.
