Given numbers are 121,308,121,424

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

The LCM of 121,308,121,424 is 359128.

Find LCM of 121,308,121,424 with Prime Factorization

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

2 x 2 x 11 x 11 x 1 x 7 x 1 x 106 = 359128

Therefore, the lowest common multiple of 121,308,121,424 is 359128.

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 308 x 121 x 424 = 1911997472

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

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

121 : 1, 11, 121

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,308,121,424, is 1.

Now, the common factors can be found like this.

121:11x 11

308:2x 2x 7x 11

121:11x 11

424:2x 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.

2x 2x 11x 11x 11 = 5324

Therefore, the value for common factors is 5324.

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 = 1911997472/(1x5324)

LCM = 1911997472/5324

LCM = 359128

Thus, we can understand that the LCM of 121,308,121,424 is 359128.
