Given numbers are 998,237,920,55

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

The LCM of 998,237,920,55 is 1196821560.

Find LCM of 998,237,920,55 with Prime Factorization

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

2 x 5 x 499 x 237 x 92 x 11 = 1196821560

Therefore, the lowest common multiple of 998,237,920,55 is 1196821560.

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 237 x 920 x 55 = 11968215600

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

237 : 1, 3, 79, 237

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

55 : 1, 5, 11, 55

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,237,920,55, is 1.

Now, the common factors can be found like this.

998:2x 499

237:3x 79

920:2x 2x 2x 5x 23

55:5x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 11968215600/(1x10)

LCM = 11968215600/10

LCM = 1196821560

Thus, we can understand that the LCM of 998,237,920,55 is 1196821560.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 248, 415, 241, 77
