Given numbers are 755, 257, 776, 990

The list of prime factors of all numbers are

Prime factors of 755 are 5 x 151

Prime factors of 257 are 257

Prime factors of 776 are 2 x 2 x 2 x 97

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 755, 257, 776, 990

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

Apply this formula for all numbers.

Step1:

LCM(755, 257) = 194035

GCD(755, 257) = ( 755 x 257 ) / 194035

= 755 / 257

= 755

Step2:

LCM(1, 776) = 776

GCD(1, 776) = ( 1 x 776 ) / 776

= 1 / 776

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 755, 257, 776, 990 is 1
