Calculate the LCM of 981,385,903

Given numbers are 981,385,903

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

The LCM of 981,385,903 is 16240455.

Find LCM of 981,385,903 with Prime Factorization


3 981, 385, 903
7 327, 385, 301
327, 55, 43

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

3 x 7 x 327 x 55 x 43 = 16240455

Therefore, the lowest common multiple of 981,385,903 is 16240455.

LCM Formula to Find Lowest Common Multiple of 981,385,903

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 385 x 903 = 341049555

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

385 : 1, 5, 7, 11, 35, 55, 77, 385

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,385,903, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

385:5x 7x 11

903:3x 7x 43

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 341049555/(1x21)

LCM = 341049555/21

LCM = 16240455

Thus, we can understand that the LCM of 981,385,903 is 16240455.
