Given numbers are 991,654,547,981

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

The LCM of 991,654,547,981 is 1063555074.

Find LCM of 991,654,547,981 with Prime Factorization

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

3 x 109 x 991 x 2 x 547 x 3 = 1063555074

Therefore, the lowest common multiple of 991,654,547,981 is 1063555074.

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.

991 x 654 x 547 x 981 = 347782509198

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.

991 : 1, 991

654 : 1, 2, 3, 6, 109, 218, 327, 654

547 : 1, 547

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,654,547,981, is 1.

Now, the common factors can be found like this.

991:991

654:2x 3x 109

547:547

981:3x 3x 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 = 347782509198/(1x327)

LCM = 347782509198/327

LCM = 1063555074

Thus, we can understand that the LCM of 991,654,547,981 is 1063555074.
