Given numbers are 977, 305, 233, 687

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

Apply this formula for all numbers.

Step1:

LCM(977, 305) = 297985

GCD(977, 305) = ( 977 x 305 ) / 297985

= 977 / 305

= 977

Step2:

LCM(1, 233) = 233

GCD(1, 233) = ( 1 x 233 ) / 233

= 1 / 233

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 977, 305, 233, 687 is 1
