Given numbers are 165, 470, 759, 621

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

Apply this formula for all numbers.

Step1:

LCM(165, 470) = 15510

GCD(165, 470) = ( 165 x 470 ) / 15510

= 165 / 470

= 165

Step2:

LCM(5, 759) = 3795

GCD(5, 759) = ( 5 x 759 ) / 3795

= 5 / 759

= 5

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 165, 470, 759, 621 is 1
