Calculate the LCM of 205,921,429,702

Given numbers are 205,921,429,702

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

The LCM of 205,921,429,702 is 485984070.

Find LCM of 205,921,429,702 with Prime Factorization


3 205, 921, 429, 702
13 205, 307, 143, 234
205, 307, 11, 18

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

3 x 13 x 205 x 307 x 11 x 18 = 485984070

Therefore, the lowest common multiple of 205,921,429,702 is 485984070.

LCM Formula to Find Lowest Common Multiple of 205,921,429,702

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.

205 x 921 x 429 x 702 = 56860136190

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.

205 : 1, 5, 41, 205

921 : 1, 3, 307, 921

429 : 1, 3, 11, 13, 33, 39, 143, 429

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 205,921,429,702, is 1.

Now, the common factors can be found like this.

205:5x 41

921:3x 307

429:3x 11x 13

702:2x 3x 3x 3x 13

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 13 = 117

Therefore, the value for common factors is 117.

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 = 56860136190/(1x117)

LCM = 56860136190/117

LCM = 485984070

Thus, we can understand that the LCM of 205,921,429,702 is 485984070.
