Given numbers are 394,197,521,931

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

The LCM of 394,197,521,931 is 191110094.

Find LCM of 394,197,521,931 with Prime Factorization

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

197 x 2 x 1 x 521 x 931 = 191110094

Therefore, the lowest common multiple of 394,197,521,931 is 191110094.

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.

394 x 197 x 521 x 931 = 37648688518

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.

394 : 1, 2, 197, 394

197 : 1, 197

521 : 1, 521

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,197,521,931, is 1.

Now, the common factors can be found like this.

394:2x 197

197:197

521:521

931:7x 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.

197 = 197

Therefore, the value for common factors is 197.

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 = 37648688518/(1x197)

LCM = 37648688518/197

LCM = 191110094

Thus, we can understand that the LCM of 394,197,521,931 is 191110094.
