Calculate the LCM of 981,372,465,205

Given numbers are 981,372,465,205

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

The LCM of 981,372,465,205 is 24937020.

Find LCM of 981,372,465,205 with Prime Factorization


3 981, 372, 465, 205
5 327, 124, 155, 205
31 327, 124, 31, 41
327, 4, 1, 41

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

3 x 5 x 31 x 327 x 4 x 1 x 41 = 24937020

Therefore, the lowest common multiple of 981,372,465,205 is 24937020.

LCM Formula to Find Lowest Common Multiple of 981,372,465,205

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.

981 x 372 x 465 x 205 = 34787142900

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.

981 : 1, 3, 9, 109, 327, 981

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

465 : 1, 3, 5, 15, 31, 93, 155, 465

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,372,465,205, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

372:2x 2x 3x 31

465:3x 5x 31

205:5x 41

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 5x 31 = 1395

Therefore, the value for common factors is 1395.

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 = 34787142900/(1x1395)

LCM = 34787142900/1395

LCM = 24937020

Thus, we can understand that the LCM of 981,372,465,205 is 24937020.
