Given numbers are 991,653,478,542

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

The LCM of 991,653,478,542 is 83827019174.

Find LCM of 991,653,478,542 with Prime Factorization

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

2 x 991 x 653 x 239 x 271 = 83827019174

Therefore, the lowest common multiple of 991,653,478,542 is 83827019174.

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 653 x 478 x 542 = 167654038348

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

653 : 1, 653

478 : 1, 2, 239, 478

542 : 1, 2, 271, 542

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,653,478,542, is 1.

Now, the common factors can be found like this.

991:991

653:653

478:2x 239

542:2x 271

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

2 = 2

Therefore, the value for common factors is 2.

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 = 167654038348/(1x2)

LCM = 167654038348/2

LCM = 83827019174

Thus, we can understand that the LCM of 991,653,478,542 is 83827019174.
