Given numbers are 121,429,209,797

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

The LCM of 121,429,209,797 is 71459817.

Find LCM of 121,429,209,797 with Prime Factorization

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

11 x 11 x 39 x 19 x 797 = 71459817

Therefore, the lowest common multiple of 121,429,209,797 is 71459817.

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 429 x 209 x 797 = 8646637857

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

429 : 1, 3, 11, 13, 33, 39, 143, 429

209 : 1, 11, 19, 209

797 : 1, 797

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,429,209,797, is 1.

Now, the common factors can be found like this.

121:11x 11

429:3x 11x 13

209:11x 19

797:797

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 = 8646637857/(1x121)

LCM = 8646637857/121

LCM = 71459817

Thus, we can understand that the LCM of 121,429,209,797 is 71459817.
