Given numbers are 427,193,361,399

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

The LCM of 427,193,361,399 is 89251113.

Find LCM of 427,193,361,399 with Prime Factorization

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

7 x 19 x 61 x 193 x 19 x 3 = 89251113

Therefore, the lowest common multiple of 427,193,361,399 is 89251113.

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 193 x 361 x 399 = 11870398029

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

193 : 1, 193

361 : 1, 19, 361

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,193,361,399, is 1.

Now, the common factors can be found like this.

427:7x 61

193:193

361:19x 19

399:3x 7x 19

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

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 11870398029/(1x133)

LCM = 11870398029/133

LCM = 89251113

Thus, we can understand that the LCM of 427,193,361,399 is 89251113.
