Given numbers are 998,311,161,161

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

The LCM of 998,311,161,161 is 49970858.

Find LCM of 998,311,161,161 with Prime Factorization

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

7 x 23 x 998 x 311 x 1 x 1 = 49970858

Therefore, the lowest common multiple of 998,311,161,161 is 49970858.

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.

998 x 311 x 161 x 161 = 8045308138

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.

998 : 1, 2, 499, 998

311 : 1, 311

161 : 1, 7, 23, 161

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,311,161,161, is 1.

Now, the common factors can be found like this.

998:2x 499

311:311

161:7x 23

161:7x 23

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 8045308138/(1x161)

LCM = 8045308138/161

LCM = 49970858

Thus, we can understand that the LCM of 998,311,161,161 is 49970858.
