Given numbers are 161,989,115,424

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

The LCM of 161,989,115,424 is 14676760.

Find LCM of 161,989,115,424 with Prime Factorization

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

23 x 7 x 43 x 5 x 424 = 14676760

Therefore, the lowest common multiple of 161,989,115,424 is 14676760.

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 989 x 115 x 424 = 7764006040

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

989 : 1, 23, 43, 989

115 : 1, 5, 23, 115

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,989,115,424, is 1.

Now, the common factors can be found like this.

161:7x 23

989:23x 43

115:5x 23

424:2x 2x 2x 53

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 7764006040/(1x529)

LCM = 7764006040/529

LCM = 14676760

Thus, we can understand that the LCM of 161,989,115,424 is 14676760.
