Given numbers are 285,178,998,122

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

The LCM of 285,178,998,122 is 1544170470.

Find LCM of 285,178,998,122 with Prime Factorization

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

2 x 285 x 89 x 499 x 61 = 1544170470

Therefore, the lowest common multiple of 285,178,998,122 is 1544170470.

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.

285 x 178 x 998 x 122 = 6176681880

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

178 : 1, 2, 89, 178

998 : 1, 2, 499, 998

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,178,998,122, is 1.

Now, the common factors can be found like this.

285:3x 5x 19

178:2x 89

998:2x 499

122:2x 61

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 6176681880/(1x4)

LCM = 6176681880/4

LCM = 1544170470

Thus, we can understand that the LCM of 285,178,998,122 is 1544170470.
