Given numbers are 162,178,778,966

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

The LCM of 162,178,778,966 is 902984922.

Find LCM of 162,178,778,966 with Prime Factorization

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

2 x 3 x 27 x 89 x 389 x 161 = 902984922

Therefore, the lowest common multiple of 162,178,778,966 is 902984922.

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.

162 x 178 x 778 x 966 = 21671638128

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.

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

178 : 1, 2, 89, 178

778 : 1, 2, 389, 778

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,178,778,966, is 2.

Now, the common factors can be found like this.

162:2x 3x 3x 3x 3

178:2x 89

778:2x 389

966:2x 3x 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.

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 21671638128/(2x12)

LCM = 21671638128/24

LCM = 902984922

Thus, we can understand that the LCM of 162,178,778,966 is 902984922.
