Given numbers are 981,393,953,872

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

The LCM of 981,393,953,872 is 979767864.

Find LCM of 981,393,953,872 with Prime Factorization

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

3 x 109 x 3 x 131 x 953 x 8 = 979767864

Therefore, the lowest common multiple of 981,393,953,872 is 979767864.

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 393 x 953 x 872 = 320384091528

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

393 : 1, 3, 131, 393

953 : 1, 953

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,393,953,872, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

393:3x 131

953:953

872:2x 2x 2x 109

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

3x 109 = 327

Therefore, the value for common factors is 327.

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 = 320384091528/(1x327)

LCM = 320384091528/327

LCM = 979767864

Thus, we can understand that the LCM of 981,393,953,872 is 979767864.
