Given numbers are 991,565,910,865

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

The LCM of 991,565,910,865 is 17629483690.

Find LCM of 991,565,910,865 with Prime Factorization

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

5 x 991 x 113 x 182 x 173 = 17629483690

Therefore, the lowest common multiple of 991,565,910,865 is 17629483690.

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.

991 x 565 x 910 x 865 = 440737092250

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.

991 : 1, 991

565 : 1, 5, 113, 565

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,565,910,865, is 1.

Now, the common factors can be found like this.

991:991

565:5x 113

910:2x 5x 7x 13

865:5x 173

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 440737092250/(1x25)

LCM = 440737092250/25

LCM = 17629483690

Thus, we can understand that the LCM of 991,565,910,865 is 17629483690.

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

• LCM of 240, 155, 342, 406
