Given numbers are 454,555,227,221

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

The LCM of 454,555,227,221 is 55685370.

Find LCM of 454,555,227,221 with Prime Factorization

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

227 x 2 x 555 x 1 x 221 = 55685370

Therefore, the lowest common multiple of 454,555,227,221 is 55685370.

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.

454 x 555 x 227 x 221 = 12640578990

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.

454 : 1, 2, 227, 454

555 : 1, 3, 5, 15, 37, 111, 185, 555

227 : 1, 227

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,555,227,221, is 1.

Now, the common factors can be found like this.

454:2x 227

555:3x 5x 37

227:227

221:13x 17

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

227 = 227

Therefore, the value for common factors is 227.

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 = 12640578990/(1x227)

LCM = 12640578990/227

LCM = 55685370

Thus, we can understand that the LCM of 454,555,227,221 is 55685370.
