Given numbers are 445,498,138,457

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

The LCM of 445,498,138,457 is 2329342710.

Find LCM of 445,498,138,457 with Prime Factorization

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

2 x 3 x 445 x 83 x 23 x 457 = 2329342710

Therefore, the lowest common multiple of 445,498,138,457 is 2329342710.

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.

445 x 498 x 138 x 457 = 13976056260

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.

445 : 1, 5, 89, 445

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,498,138,457, is 1.

Now, the common factors can be found like this.

445:5x 89

498:2x 3x 83

138:2x 3x 23

457:457

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 13976056260/(1x6)

LCM = 13976056260/6

LCM = 2329342710

Thus, we can understand that the LCM of 445,498,138,457 is 2329342710.
