Given numbers are 870, 531, 243, 994

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 531 are 3 x 3 x 59

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 994 are 2 x 7 x 71

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 870, 531, 243, 994

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(870, 531) = 153990

GCD(870, 531) = ( 870 x 531 ) / 153990

= 870 / 531

= 870

Step2:

LCM(3, 243) = 243

GCD(3, 243) = ( 3 x 243 ) / 243

= 3 / 243

= 3

Step3:

LCM(3, 994) = 2982

GCD(3, 994) = ( 3 x 994 ) / 2982

= 3 / 994

= 3

So, Greatest Common Divisor of 870, 531, 243, 994 is 1
