Calculate the LCM of 987,399,363,623

Given numbers are 987,399,363,623

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

The LCM of 987,399,363,623 is 201951057.

Find LCM of 987,399,363,623 with Prime Factorization


3 987, 399, 363, 623
7 329, 133, 121, 623
47, 19, 121, 89

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

3 x 7 x 47 x 19 x 121 x 89 = 201951057

Therefore, the lowest common multiple of 987,399,363,623 is 201951057.

LCM Formula to Find Lowest Common Multiple of 987,399,363,623

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.

987 x 399 x 363 x 623 = 89060416137

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.

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

399 : 1, 3, 7, 19, 21, 57, 133, 399

363 : 1, 3, 11, 33, 121, 363

623 : 1, 7, 89, 623

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,399,363,623, is 1.

Now, the common factors can be found like this.

987:3x 7x 47

399:3x 7x 19

363:3x 11x 11

623:7x 89

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 7x 7 = 441

Therefore, the value for common factors is 441.

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 = 89060416137/(1x441)

LCM = 89060416137/441

LCM = 201951057

Thus, we can understand that the LCM of 987,399,363,623 is 201951057.
