Given numbers are 277, 381, 819, 980

The list of prime factors of all numbers are

Prime factors of 277 are 277

Prime factors of 381 are 3 x 127

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 277, 381, 819, 980

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

Apply this formula for all numbers.

Step1:

LCM(277, 381) = 105537

GCD(277, 381) = ( 277 x 381 ) / 105537

= 277 / 381

= 277

Step2:

LCM(1, 819) = 819

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

= 1 / 819

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 277, 381, 819, 980 is 1
