Given numbers are 161,847,939,943

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

The LCM of 161,847,939,943 is 749999019.

Find LCM of 161,847,939,943 with Prime Factorization

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

7 x 23 x 1 x 121 x 939 x 41 = 749999019

Therefore, the lowest common multiple of 161,847,939,943 is 749999019.

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 847 x 939 x 943 = 120749842059

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

847 : 1, 7, 11, 77, 121, 847

939 : 1, 3, 313, 939

943 : 1, 23, 41, 943

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,847,939,943, is 1.

Now, the common factors can be found like this.

161:7x 23

847:7x 11x 11

939:3x 313

943:23x 41

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

7x 23 = 161

Therefore, the value for common factors is 161.

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 = 120749842059/(1x161)

LCM = 120749842059/161

LCM = 749999019

Thus, we can understand that the LCM of 161,847,939,943 is 749999019.
