Given numbers are 421, 761, 977, 819

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

Apply this formula for all numbers.

Step1:

LCM(421, 761) = 320381

GCD(421, 761) = ( 421 x 761 ) / 320381

= 421 / 761

= 421

Step2:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 421, 761, 977, 819 is 1
