Given numbers are 168, 420, 536, 525

The list of prime factors of all numbers are

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 536 are 2 x 2 x 2 x 67

Prime factors of 525 are 3 x 5 x 5 x 7

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

Given numbers are 168, 420, 536, 525

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

Apply this formula for all numbers.

Step1:

LCM(168, 420) = 840

GCD(168, 420) = ( 168 x 420 ) / 840

= 168 / 420

= 168

Step2:

LCM(84, 536) = 11256

GCD(84, 536) = ( 84 x 536 ) / 11256

= 84 / 536

= 84

Step3:

LCM(4, 525) = 2100

GCD(4, 525) = ( 4 x 525 ) / 2100

= 4 / 525

= 4

So, Greatest Common Divisor of 168, 420, 536, 525 is 1
