Given numbers are 517,521,473,991

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

The LCM of 517,521,473,991 is 11478109841.

Find LCM of 517,521,473,991 with Prime Factorization

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

11 x 47 x 521 x 43 x 991 = 11478109841

Therefore, the lowest common multiple of 517,521,473,991 is 11478109841.

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.

517 x 521 x 473 x 991 = 126259208251

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.

517 : 1, 11, 47, 517

521 : 1, 521

473 : 1, 11, 43, 473

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,521,473,991, is 1.

Now, the common factors can be found like this.

517:11x 47

521:521

473:11x 43

991:991

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

11 = 11

Therefore, the value for common factors is 11.

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 = 126259208251/(1x11)

LCM = 126259208251/11

LCM = 11478109841

Thus, we can understand that the LCM of 517,521,473,991 is 11478109841.
