Given numbers are 161,803,919,115,789

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

The LCM of 161,803,919,115,789 is 468709698765.

Find LCM of 161,803,919,115,789 with Prime Factorization

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

23 x 7 x 803 x 919 x 5 x 789 = 468709698765

Therefore, the lowest common multiple of 161,803,919,115,789 is 468709698765.

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.

161 x 803 x 919 x 115 x 789 = 10780323071595

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.

161 : 1, 7, 23, 161

803 : 1, 11, 73, 803

919 : 1, 919

115 : 1, 5, 23, 115

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,803,919,115,789, is 1.

Now, the common factors can be found like this.

161:7x 23

803:11x 73

919:919

115:5x 23

789:3x 263

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

23 = 23

Therefore, the value for common factors is 23.

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 = 10780323071595/(1x23)

LCM = 10780323071595/23

LCM = 468709698765

Thus, we can understand that the LCM of 161,803,919,115,789 is 468709698765.
