Given numbers are 121,759,161,361

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

The LCM of 121,759,161,361 is 21097923.

Find LCM of 121,759,161,361 with Prime Factorization

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

11 x 23 x 11 x 3 x 7 x 361 = 21097923

Therefore, the lowest common multiple of 121,759,161,361 is 21097923.

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 759 x 161 x 361 = 5337774519

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

759 : 1, 3, 11, 23, 33, 69, 253, 759

161 : 1, 7, 23, 161

361 : 1, 19, 361

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,759,161,361, is 1.

Now, the common factors can be found like this.

121:11x 11

759:3x 11x 23

161:7x 23

361:19x 19

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

11x 23 = 253

Therefore, the value for common factors is 253.

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 = 5337774519/(1x253)

LCM = 5337774519/253

LCM = 21097923

Thus, we can understand that the LCM of 121,759,161,361 is 21097923.
