Given numbers are 531, 550, 163, 686

The list of prime factors of all numbers are

Prime factors of 531 are 3 x 3 x 59

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 163 are 163

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 531, 550, 163, 686

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

Apply this formula for all numbers.

Step1:

LCM(531, 550) = 292050

GCD(531, 550) = ( 531 x 550 ) / 292050

= 531 / 550

= 531

Step2:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 531, 550, 163, 686 is 1
