Given numbers are 165, 925, 39, 428

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

Apply this formula for all numbers.

Step1:

LCM(165, 925) = 30525

GCD(165, 925) = ( 165 x 925 ) / 30525

= 165 / 925

= 165

Step2:

LCM(5, 39) = 195

GCD(5, 39) = ( 5 x 39 ) / 195

= 5 / 39

= 5

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 165, 925, 39, 428 is 1
