Calculate the LCM of 342,520,939,969

Given numbers are 342,520,939,969

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

The LCM of 342,520,939,969 is 473143320.

Find LCM of 342,520,939,969 with Prime Factorization


2 342, 520, 939, 969
3 171, 260, 939, 969
19 57, 260, 313, 323
3, 260, 313, 17

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

2 x 3 x 19 x 3 x 260 x 313 x 17 = 473143320

Therefore, the lowest common multiple of 342,520,939,969 is 473143320.

LCM Formula to Find Lowest Common Multiple of 342,520,939,969

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.

342 x 520 x 939 x 969 = 161815015440

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.

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

939 : 1, 3, 313, 939

969 : 1, 3, 17, 19, 51, 57, 323, 969

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,520,939,969, is 1.

Now, the common factors can be found like this.

342:2x 3x 3x 19

520:2x 2x 2x 5x 13

939:3x 313

969:3x 17x 19

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 3x 19 = 342

Therefore, the value for common factors is 342.

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 = 161815015440/(1x342)

LCM = 161815015440/342

LCM = 473143320

Thus, we can understand that the LCM of 342,520,939,969 is 473143320.
