Calculate the LCM of 297,960,874,921

Given numbers are 297,960,874,921

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

The LCM of 297,960,874,921 is 12750471360.

Find LCM of 297,960,874,921 with Prime Factorization


2 297, 960, 874, 921
3 297, 480, 437, 921
99, 160, 437, 307

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

2 x 3 x 99 x 160 x 437 x 307 = 12750471360

Therefore, the lowest common multiple of 297,960,874,921 is 12750471360.

LCM Formula to Find Lowest Common Multiple of 297,960,874,921

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.

297 x 960 x 874 x 921 = 229508484480

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.

297 : 1, 3, 9, 11, 27, 33, 99, 297

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

874 : 1, 2, 19, 23, 38, 46, 437, 874

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,960,874,921, is 1.

Now, the common factors can be found like this.

297:3x 3x 3x 11

960:2x 2x 2x 2x 2x 2x 3x 5

874:2x 19x 23

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.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 229508484480/(1x18)

LCM = 229508484480/18

LCM = 12750471360

Thus, we can understand that the LCM of 297,960,874,921 is 12750471360.
