Given numbers are 204, 530, 87, 172

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

Apply this formula for all numbers.

Step1:

LCM(204, 530) = 54060

GCD(204, 530) = ( 204 x 530 ) / 54060

= 204 / 530

= 204

Step2:

LCM(2, 87) = 174

GCD(2, 87) = ( 2 x 87 ) / 174

= 2 / 87

= 2

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 204, 530, 87, 172 is 1
