Given numbers are 998,371,661,661

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

The LCM of 998,371,661,661 is 244740538.

Find LCM of 998,371,661,661 with Prime Factorization

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

661 x 998 x 371 x 1 x 1 = 244740538

Therefore, the lowest common multiple of 998,371,661,661 is 244740538.

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 371 x 661 x 661 = 161773495618

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

371 : 1, 7, 53, 371

661 : 1, 661

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,371,661,661, is 1.

Now, the common factors can be found like this.

998:2x 499

371:7x 53

661:661

661:661

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

661 = 661

Therefore, the value for common factors is 661.

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 = 161773495618/(1x661)

LCM = 161773495618/661

LCM = 244740538

Thus, we can understand that the LCM of 998,371,661,661 is 244740538.
