Given numbers are 121,209,361,212

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

The LCM of 121,209,361,212 is 9260372.

Find LCM of 121,209,361,212 with Prime Factorization

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

11 x 19 x 11 x 1 x 19 x 212 = 9260372

Therefore, the lowest common multiple of 121,209,361,212 is 9260372.

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 209 x 361 x 212 = 1935417748

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

209 : 1, 11, 19, 209

361 : 1, 19, 361

212 : 1, 2, 4, 53, 106, 212

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,209,361,212, is 1.

Now, the common factors can be found like this.

121:11x 11

209:11x 19

361:19x 19

212:2x 2x 53

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 1935417748/(1x209)

LCM = 1935417748/209

LCM = 9260372

Thus, we can understand that the LCM of 121,209,361,212 is 9260372.
