Calculate the LCM of 531,159,570,285

Given numbers are 531,159,570,285

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

The LCM of 531,159,570,285 is 5347170.

Find LCM of 531,159,570,285 with Prime Factorization


3 531, 159, 570, 285
5 177, 53, 190, 95
19 177, 53, 38, 19
177, 53, 2, 1

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

3 x 5 x 19 x 177 x 53 x 2 x 1 = 5347170

Therefore, the lowest common multiple of 531,159,570,285 is 5347170.

LCM Formula to Find Lowest Common Multiple of 531,159,570,285

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.

531 x 159 x 570 x 285 = 13715491050

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.

531 : 1, 3, 9, 59, 177, 531

159 : 1, 3, 53, 159

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

285 : 1, 3, 5, 15, 19, 57, 95, 285

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,159,570,285, is 3.

Now, the common factors can be found like this.

531:3x 3x 59

159:3x 53

570:2x 3x 5x 19

285:3x 5x 19

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 5x 19 = 855

Therefore, the value for common factors is 855.

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 = 13715491050/(3x855)

LCM = 13715491050/2565

LCM = 5347170

Thus, we can understand that the LCM of 531,159,570,285 is 5347170.
