Given numbers are 121,242,272,238,155

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

The LCM of 121,242,272,238,155 is 35709520.

Find LCM of 121,242,272,238,155 with Prime Factorization

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

2 x 11 x 11 x 17 x 1 x 1 x 8 x 7 x 155 = 35709520

Therefore, the lowest common multiple of 121,242,272,238,155 is 35709520.

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 242 x 272 x 238 x 155 = 293817930560

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

242 : 1, 2, 11, 22, 121, 242

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

238 : 1, 2, 7, 14, 17, 34, 119, 238

155 : 1, 5, 31, 155

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,242,272,238,155, is 1.

Now, the common factors can be found like this.

121:11x 11

242:2x 11x 11

272:2x 2x 2x 2x 17

238:2x 7x 17

155:5x 31

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

2x 2x 11x 11x 17 = 8228

Therefore, the value for common factors is 8228.

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 = 293817930560/(1x8228)

LCM = 293817930560/8228

LCM = 35709520

Thus, we can understand that the LCM of 121,242,272,238,155 is 35709520.
