Given numbers are 227,121,170,454

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

The LCM of 227,121,170,454 is 4669390.

Find LCM of 227,121,170,454 with Prime Factorization

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

2 x 227 x 1 x 121 x 85 x 1 = 4669390

Therefore, the lowest common multiple of 227,121,170,454 is 4669390.

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.

227 x 121 x 170 x 454 = 2119903060

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.

227 : 1, 227

121 : 1, 11, 121

170 : 1, 2, 5, 10, 17, 34, 85, 170

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 227,121,170,454, is 1.

Now, the common factors can be found like this.

227:227

121:11x 11

170:2x 5x 17

454:2x 227

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

2x 227 = 454

Therefore, the value for common factors is 454.

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 = 2119903060/(1x454)

LCM = 2119903060/454

LCM = 4669390

Thus, we can understand that the LCM of 227,121,170,454 is 4669390.
