Given numbers are 117,411,385,217

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

The LCM of 117,411,385,217 is 191306115.

Find LCM of 117,411,385,217 with Prime Factorization

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

3 x 7 x 39 x 137 x 55 x 31 = 191306115

Therefore, the lowest common multiple of 117,411,385,217 is 191306115.

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.

117 x 411 x 385 x 217 = 4017428415

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.

117 : 1, 3, 9, 13, 39, 117

411 : 1, 3, 137, 411

385 : 1, 5, 7, 11, 35, 55, 77, 385

217 : 1, 7, 31, 217

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,411,385,217, is 1.

Now, the common factors can be found like this.

117:3x 3x 13

411:3x 137

385:5x 7x 11

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.

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 4017428415/(1x21)

LCM = 4017428415/21

LCM = 191306115

Thus, we can understand that the LCM of 117,411,385,217 is 191306115.
