Given numbers are 121,161,481,109,871

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

The LCM of 121,161,481,109,871 is 68431746383.

Find LCM of 121,161,481,109,871 with Prime Factorization

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

13 x 121 x 161 x 37 x 109 x 67 = 68431746383

Therefore, the lowest common multiple of 121,161,481,109,871 is 68431746383.

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.

121 x 161 x 481 x 109 x 871 = 889612702979

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.

121 : 1, 11, 121

161 : 1, 7, 23, 161

481 : 1, 13, 37, 481

109 : 1, 109

871 : 1, 13, 67, 871

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,161,481,109,871, is 1.

Now, the common factors can be found like this.

121:11x 11

161:7x 23

481:13x 37

109:109

871:13x 67

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

13 = 13

Therefore, the value for common factors is 13.

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 = 889612702979/(1x13)

LCM = 889612702979/13

LCM = 68431746383

Thus, we can understand that the LCM of 121,161,481,109,871 is 68431746383.
