Given numbers are 621, 938, 90, 775

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

Apply this formula for all numbers.

Step1:

LCM(621, 938) = 582498

GCD(621, 938) = ( 621 x 938 ) / 582498

= 621 / 938

= 621

Step2:

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

= 1 / 90

= 1

Step3:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

So, Greatest Common Divisor of 621, 938, 90, 775 is 1
