Calculate the LCM of 206,987,141,361

Given numbers are 206,987,141,361

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

The LCM of 206,987,141,361 is 73399242.

Find LCM of 206,987,141,361 with Prime Factorization


3 206, 987, 141, 361
47 206, 329, 47, 361
206, 7, 1, 361

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

3 x 47 x 206 x 7 x 1 x 361 = 73399242

Therefore, the lowest common multiple of 206,987,141,361 is 73399242.

LCM Formula to Find Lowest Common Multiple of 206,987,141,361

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.

206 x 987 x 141 x 361 = 10349293122

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.

206 : 1, 2, 103, 206

987 : 1, 3, 7, 21, 47, 141, 329, 987

141 : 1, 3, 47, 141

361 : 1, 19, 361

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 206,987,141,361, is 1.

Now, the common factors can be found like this.

206:2x 103

987:3x 7x 47

141:3x 47

361:19x 19

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

3x 47 = 141

Therefore, the value for common factors is 141.

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 = 10349293122/(1x141)

LCM = 10349293122/141

LCM = 73399242

Thus, we can understand that the LCM of 206,987,141,361 is 73399242.
