Given numbers are 422, 255, 260, 977

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

Apply this formula for all numbers.

Step1:

LCM(422, 255) = 107610

GCD(422, 255) = ( 422 x 255 ) / 107610

= 422 / 255

= 422

Step2:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

Step3:

LCM(1, 977) = 977

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

= 1 / 977

= 1

So, Greatest Common Divisor of 422, 255, 260, 977 is 1
