Given numbers are 221,213,485,284

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

The LCM of 221,213,485,284 is 91321620.

Find LCM of 221,213,485,284 with Prime Factorization

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

71 x 221 x 3 x 485 x 4 = 91321620

Therefore, the lowest common multiple of 221,213,485,284 is 91321620.

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.

221 x 213 x 485 x 284 = 6483835020

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.

221 : 1, 13, 17, 221

213 : 1, 3, 71, 213

485 : 1, 5, 97, 485

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,213,485,284, is 1.

Now, the common factors can be found like this.

221:13x 17

213:3x 71

485:5x 97

284:2x 2x 71

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

71 = 71

Therefore, the value for common factors is 71.

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 = 6483835020/(1x71)

LCM = 6483835020/71

LCM = 91321620

Thus, we can understand that the LCM of 221,213,485,284 is 91321620.
