Given numbers are 117,991,169,897

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

The LCM of 117,991,169,897 is 34668153.

Find LCM of 117,991,169,897 with Prime Factorization

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

3 x 13 x 3 x 991 x 13 x 23 = 34668153

Therefore, the lowest common multiple of 117,991,169,897 is 34668153.

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 991 x 169 x 897 = 17576753571

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

991 : 1, 991

169 : 1, 13, 169

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,991,169,897, is 1.

Now, the common factors can be found like this.

117:3x 3x 13

991:991

169:13x 13

897:3x 13x 23

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

3x 13x 13 = 507

Therefore, the value for common factors is 507.

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 = 17576753571/(1x507)

LCM = 17576753571/507

LCM = 34668153

Thus, we can understand that the LCM of 117,991,169,897 is 34668153.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 231, 320, 405, 368
