Calculate the LCM of 209,770,818,312,243

Given numbers are 209,770,818,312,243

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

The LCM of 209,770,818,312,243 is 75609654120.

Find LCM of 209,770,818,312,243 with Prime Factorization


2 209, 770, 818, 312, 243
3 209, 385, 409, 156, 243
11 209, 385, 409, 52, 81
19, 35, 409, 52, 81

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

2 x 3 x 11 x 19 x 35 x 409 x 52 x 81 = 75609654120

Therefore, the lowest common multiple of 209,770,818,312,243 is 75609654120.

LCM Formula to Find Lowest Common Multiple of 209,770,818,312,243

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.

209 x 770 x 818 x 312 x 243 = 9980474343840

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.

209 : 1, 11, 19, 209

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

818 : 1, 2, 409, 818

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

243 : 1, 3, 9, 27, 81, 243

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,770,818,312,243, is 1.

Now, the common factors can be found like this.

209:11x 19

770:2x 5x 7x 11

818:2x 409

312:2x 2x 2x 3x 13

243:3x 3x 3x 3x 3

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

2x 2x 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 9980474343840/(1x132)

LCM = 9980474343840/132

LCM = 75609654120

Thus, we can understand that the LCM of 209,770,818,312,243 is 75609654120.
