Given numbers are 427,162,221,221

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

The LCM of 427,162,221,221 is 15287454.

Find LCM of 427,162,221,221 with Prime Factorization

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

13 x 17 x 427 x 162 x 1 x 1 = 15287454

Therefore, the lowest common multiple of 427,162,221,221 is 15287454.

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.

427 x 162 x 221 x 221 = 3378527334

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.

427 : 1, 7, 61, 427

162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162

221 : 1, 13, 17, 221

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,162,221,221, is 1.

Now, the common factors can be found like this.

427:7x 61

162:2x 3x 3x 3x 3

221:13x 17

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.

13x 17 = 221

Therefore, the value for common factors is 221.

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 = 3378527334/(1x221)

LCM = 3378527334/221

LCM = 15287454

Thus, we can understand that the LCM of 427,162,221,221 is 15287454.
