Given numbers are 538,611,611,217

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

The LCM of 538,611,611,217 is 71331806.

Find LCM of 538,611,611,217 with Prime Factorization

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

13 x 47 x 538 x 1 x 1 x 217 = 71331806

Therefore, the lowest common multiple of 538,611,611,217 is 71331806.

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.

538 x 611 x 611 x 217 = 43583733466

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.

538 : 1, 2, 269, 538

611 : 1, 13, 47, 611

611 : 1, 13, 47, 611

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,611,611,217, is 1.

Now, the common factors can be found like this.

538:2x 269

611:13x 47

611:13x 47

217:7x 31

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

13x 47 = 611

Therefore, the value for common factors is 611.

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 = 43583733466/(1x611)

LCM = 43583733466/611

LCM = 71331806

Thus, we can understand that the LCM of 538,611,611,217 is 71331806.
