Given numbers are 455,661,121,661

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

The LCM of 455,661,121,661 is 36391355.

Find LCM of 455,661,121,661 with Prime Factorization

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

661 x 455 x 1 x 121 x 1 = 36391355

Therefore, the lowest common multiple of 455,661,121,661 is 36391355.

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.

455 x 661 x 121 x 661 = 24054685655

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

661 : 1, 661

121 : 1, 11, 121

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,661,121,661, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

661:661

121:11x 11

661:661

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

661 = 661

Therefore, the value for common factors is 661.

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 = 24054685655/(1x661)

LCM = 24054685655/661

LCM = 36391355

Thus, we can understand that the LCM of 455,661,121,661 is 36391355.
