Given numbers are 538,158,209,121

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

The LCM of 538,158,209,121 is 97712098.

Find LCM of 538,158,209,121 with Prime Factorization

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

2 x 11 x 269 x 79 x 19 x 11 = 97712098

Therefore, the lowest common multiple of 538,158,209,121 is 97712098.

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.

538 x 158 x 209 x 121 = 2149666156

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.

538 : 1, 2, 269, 538

158 : 1, 2, 79, 158

209 : 1, 11, 19, 209

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,158,209,121, is 1.

Now, the common factors can be found like this.

538:2x 269

158:2x 79

209:11x 19

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.

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 2149666156/(1x22)

LCM = 2149666156/22

LCM = 97712098

Thus, we can understand that the LCM of 538,158,209,121 is 97712098.
