Given numbers are 194,620,420,794,505

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

The LCM of 194,620,420,794,505 is 50640105180.

Find LCM of 194,620,420,794,505 with Prime Factorization

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

2 x 2 x 5 x 97 x 31 x 21 x 397 x 101 = 50640105180

Therefore, the lowest common multiple of 194,620,420,794,505 is 50640105180.

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.

194 x 620 x 420 x 794 x 505 = 20256042072000

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.

194 : 1, 2, 97, 194

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

794 : 1, 2, 397, 794

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 194,620,420,794,505, is 1.

Now, the common factors can be found like this.

194:2x 97

620:2x 2x 5x 31

420:2x 2x 3x 5x 7

794:2x 397

505:5x 101

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 2x 2x 5x 5 = 400

Therefore, the value for common factors is 400.

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 = 20256042072000/(1x400)

LCM = 20256042072000/400

LCM = 50640105180

Thus, we can understand that the LCM of 194,620,420,794,505 is 50640105180.
