Given numbers are 165, 639, 905, 952

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

Apply this formula for all numbers.

Step1:

LCM(165, 639) = 35145

GCD(165, 639) = ( 165 x 639 ) / 35145

= 165 / 639

= 165

Step2:

LCM(3, 905) = 2715

GCD(3, 905) = ( 3 x 905 ) / 2715

= 3 / 905

= 3

Step3:

LCM(1, 952) = 952

GCD(1, 952) = ( 1 x 952 ) / 952

= 1 / 952

= 1

So, Greatest Common Divisor of 165, 639, 905, 952 is 1
