Given numbers are 997,538,563,558

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

The LCM of 997,538,563,558 is 84253903722.

Find LCM of 997,538,563,558 with Prime Factorization

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

2 x 997 x 269 x 563 x 279 = 84253903722

Therefore, the lowest common multiple of 997,538,563,558 is 84253903722.

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.

997 x 538 x 563 x 558 = 168507807444

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.

997 : 1, 997

538 : 1, 2, 269, 538

563 : 1, 563

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,538,563,558, is 1.

Now, the common factors can be found like this.

997:997

538:2x 269

563:563

558:2x 3x 3x 31

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 = 168507807444/(1x2)

LCM = 168507807444/2

LCM = 84253903722

Thus, we can understand that the LCM of 997,538,563,558 is 84253903722.
