Given numbers are 498,205,394,42

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

The LCM of 498,205,394,42 is 140782110.

Find LCM of 498,205,394,42 with Prime Factorization

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

2 x 3 x 83 x 205 x 197 x 7 = 140782110

Therefore, the lowest common multiple of 498,205,394,42 is 140782110.

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.

498 x 205 x 394 x 42 = 1689385320

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.

498 : 1, 2, 3, 6, 83, 166, 249, 498

205 : 1, 5, 41, 205

394 : 1, 2, 197, 394

42 : 1, 2, 3, 6, 7, 14, 21, 42

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 498,205,394,42, is 1.

Now, the common factors can be found like this.

498:2x 3x 83

205:5x 41

394:2x 197

42:2x 3x 7

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 1689385320/(1x12)

LCM = 1689385320/12

LCM = 140782110

Thus, we can understand that the LCM of 498,205,394,42 is 140782110.
