Given numbers are 197,842,520,457

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

The LCM of 197,842,520,457 is 19709148680.

Find LCM of 197,842,520,457 with Prime Factorization

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

2 x 197 x 421 x 260 x 457 = 19709148680

Therefore, the lowest common multiple of 197,842,520,457 is 19709148680.

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.

197 x 842 x 520 x 457 = 39418297360

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.

197 : 1, 197

842 : 1, 2, 421, 842

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,842,520,457, is 1.

Now, the common factors can be found like this.

197:197

842:2x 421

520:2x 2x 2x 5x 13

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 39418297360/(1x2)

LCM = 39418297360/2

LCM = 19709148680

Thus, we can understand that the LCM of 197,842,520,457 is 19709148680.
