Given numbers are 121,605,154,491

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

The LCM of 121,605,154,491 is 4158770.

Find LCM of 121,605,154,491 with Prime Factorization

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

11 x 11 x 1 x 5 x 14 x 491 = 4158770

Therefore, the lowest common multiple of 121,605,154,491 is 4158770.

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 605 x 154 x 491 = 5535322870

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

605 : 1, 5, 11, 55, 121, 605

154 : 1, 2, 7, 11, 14, 22, 77, 154

491 : 1, 491

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,605,154,491, is 1.

Now, the common factors can be found like this.

121:11x 11

605:5x 11x 11

154:2x 7x 11

491:491

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

11x 11x 11 = 1331

Therefore, the value for common factors is 1331.

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 = 5535322870/(1x1331)

LCM = 5535322870/1331

LCM = 4158770

Thus, we can understand that the LCM of 121,605,154,491 is 4158770.
