Given numbers are 531,243,978,406,440

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

The LCM of 531,243,978,406,440 is 208734676920.

Find LCM of 531,243,978,406,440 with Prime Factorization

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

2 x 3 x 3 x 59 x 27 x 163 x 203 x 220 = 208734676920

Therefore, the lowest common multiple of 531,243,978,406,440 is 208734676920.

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 243 x 978 x 406 x 440 = 22543345107360

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

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

978 : 1, 2, 3, 6, 163, 326, 489, 978

406 : 1, 2, 7, 14, 29, 58, 203, 406

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,243,978,406,440, is 1.

Now, the common factors can be found like this.

531:3x 3x 59

243:3x 3x 3x 3x 3

978:2x 3x 163

406:2x 7x 29

440:2x 2x 2x 5x 11

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 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 22543345107360/(1x108)

LCM = 22543345107360/108

LCM = 208734676920

Thus, we can understand that the LCM of 531,243,978,406,440 is 208734676920.
