Given numbers are 997,920,985

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

The LCM of 997,920,985 is 180696280.

Find LCM of 997,920,985 with Prime Factorization

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

5 x 997 x 184 x 197 = 180696280

Therefore, the lowest common multiple of 997,920,985 is 180696280.

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 920 x 985 = 903481400

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

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

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,920,985, is 1.

Now, the common factors can be found like this.

997:997

920:2x 2x 2x 5x 23

985:5x 197

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

5 = 5

Therefore, the value for common factors is 5.

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 = 903481400/(1x5)

LCM = 903481400/5

LCM = 180696280

Thus, we can understand that the LCM of 997,920,985 is 180696280.

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

• LCM of 722, 273, 792
