Given numbers are 936,683,765,921

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

The LCM of 936,683,765,921 is 16682220360.

Find LCM of 936,683,765,921 with Prime Factorization


3 936, 683, 765, 921
3 312, 683, 255, 307
104, 683, 85, 307

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

3 x 3 x 104 x 683 x 85 x 307 = 16682220360

Therefore, the lowest common multiple of 936,683,765,921 is 16682220360.

LCM Formula to Find Lowest Common Multiple of 936,683,765,921

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.

936 x 683 x 765 x 921 = 450419949720

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.

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

683 : 1, 683

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 936,683,765,921, is 1.

Now, the common factors can be found like this.

936:2x 2x 2x 3x 3x 13

683:683

765:3x 3x 5x 17

921:3x 307

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

3x 3x 3 = 27

Therefore, the value for common factors is 27.

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 = 450419949720/(1x27)

LCM = 450419949720/27

LCM = 16682220360

Thus, we can understand that the LCM of 936,683,765,921 is 16682220360.
