Given numbers are 977, 477, 503, 391

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

Apply this formula for all numbers.

Step1:

LCM(977, 477) = 466029

GCD(977, 477) = ( 977 x 477 ) / 466029

= 977 / 477

= 977

Step2:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 977, 477, 503, 391 is 1
