Given numbers are 420, 887, 626, 977

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

Apply this formula for all numbers.

Step1:

LCM(420, 887) = 372540

GCD(420, 887) = ( 420 x 887 ) / 372540

= 420 / 887

= 420

Step2:

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

= 1 / 626

= 1

Step3:

LCM(1, 977) = 977

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

= 1 / 977

= 1

So, Greatest Common Divisor of 420, 887, 626, 977 is 1
