Given numbers are 135,257,121,121

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

The LCM of 135,257,121,121 is 4198095.

Find LCM of 135,257,121,121 with Prime Factorization

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

11 x 11 x 135 x 257 x 1 x 1 = 4198095

Therefore, the lowest common multiple of 135,257,121,121 is 4198095.

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.

135 x 257 x 121 x 121 = 507969495

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.

135 : 1, 3, 5, 9, 15, 27, 45, 135

257 : 1, 257

121 : 1, 11, 121

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 135,257,121,121, is 1.

Now, the common factors can be found like this.

135:3x 3x 3x 5

257:257

121:11x 11

121:11x 11

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 507969495/(1x121)

LCM = 507969495/121

LCM = 4198095

Thus, we can understand that the LCM of 135,257,121,121 is 4198095.
